“…Das et al [1] previously reviewed experimental liquidphase densities for pyridine at saturation pressure, and noted good agreement (within 0.05%) amongst numerous sources. The value of the saturation density tabulated by Das We have converted the value of Das et al [1]to the state condition of interest by considering variations in both temperature and pressure as follows.…”

“…The injector and inlet lines were heated to 70 • C to minimize losses on the surfaces. At room temperature, the reported vapour pressure of indole is 0.012 mmHg (Das et al, 1993), which is equivalent to ∼ 16 ppmv. Therefore, most of the injected indole should have remained in the gas phase although some of it could remain adsorbed to the injection line and cham-ber wall surfaces, contributing to the variability in the SOA yield (see below).…”

Secondary organic aerosol from atmospheric photooxidation of indole

et al. 2017

Abstract. Indole is a heterocyclic compound emitted by various plant species under stressed conditions or during flowering events. The formation, optical properties, and chemical composition of secondary organic aerosol (SOA) formed by low-NO x photooxidation of indole were investigated. The SOA yield (1.3 ± 0.3) was estimated from measuring the particle mass concentration with a scanning mobility particle sizer (SMPS) and correcting it for wall loss effects. The high value of the SOA mass yield suggests that most oxidized indole products eventually end up in the particle phase. The SOA particles were collected on filters and analysed offline with UV-vis spectrophotometry to measure the mass absorption coefficient (MAC) of the bulk sample. The samples were visibly brown and had MAC values of ∼ 2 m 2 g −1 at λ = 300 nm and ∼ 0.5 m 2 g −1 at λ = 400 nm, comparable to strongly absorbing brown carbon emitted from biomass burning. The chemical composition of SOA was examined with several mass spectrometry methods. Direct analysis in real-time mass spectrometry (DART-MS) and nanospray desorption electrospray high-resolution mass spectrometry (nano-DESI-HRMS) were both used to provide information about the overall distribution of SOA compounds. High-performance liquid chromatography, coupled to photodiode array spectrophotometry and high-resolution mass spectrometry (HPLC-PDA-HRMS), was used to identify chromophoric compounds that are responsible for the brown colour of SOA. Indole derivatives, such as tryptanthrin, indirubin, indigo dye, and indoxyl red, were found to contribute significantly to the visible absorption spectrum of indole SOA. The potential effect of indole SOA on air quality was explored with an airshed model, which found elevated concentrations of indole SOA during the afternoon hours contributing considerably to the total organic aerosol under selected scenarios. Because of its high MAC values, indole SOA can contribute to decreased visibility and poor air quality.

“…Among other results good relationships with the electronegativity of the substituents have been reported. Whereas there are numerous substituted benzenes amongst this list for which there are experimental measured enthalpies of formation (Li [375], CH 3 , NH 2 , OH, F, MgBr [376] (not quite the theorist's MgH), PH 2 , SH, Cl), only the methylpyrroles have so far attracted the experimental thermochemist's attention [377]. Studies of hydroxy and mercaptopyrroles are complicated by their energetically favorable tautomerism to the corresponding pyrrolone derivative [378][379][380].…”

In this study, we relate the contents of the journal Structural Chemistry for the calendar year 2007 and thermochemistry. The year's articles were briefly summarized and a thermochemical comment written to supplement them. Frequently questions were asked and future research was suggested.Keywords Structural Chemistry Á Thermochemistry Á Thermodynamics Á Enthalpy of formation Á Enthalpy of phase change Á Enthalpy of reaction As practiced disciplines, structural chemistry and thermochemistry are very often unrelated. In this study, these disciplines are linked as relations are explicitly made using the contents of the journal Structural Chemistry (Vol. 18) for the calendar year 2007 as a scaffold for our analysis, for our selected articles in the discipline of structural chemistry. These studies have been reviewed by us, where we give them a thermochemical flavor. While this commentary is most generally written in terms of brief summaries of literature papers involving enthalpies of formation and/or reaction, not uncommonly we raise questions and even suggest possible future research. We are not, however, going to give a thermochemical slant on book reviews, honorary dedications, and obituaries although these works will be cited in our text.As such, this article is a sequel to our earlier related reviews of Structural Chemistry for the calendar years 2000 through 2004 [1-5]. Reviews for 2005 and 2006 are currently being prepared. Issue 1In the first article in the first issue of Structural Chemistry for 2007, Hargittai [6] asserted that while research is currently usually carried out in big groups, the most important ideas, observations and discoveries still belong to individuals who have to bring down dogmas or open entirely new areas in science. This may bring solace to the thermochemical community in which research groups are generally small, and the number of new practitioners sadly few.In the past decade, the crystal engineering of multidimensional arrays and networks containing metal ions has achieved considerable progress because of the increased interest in the potential utility of these compounds as zeolite-like materials [7-11], catalysts [12], or magnetic materials [13][14][15]. The thermochemistry of these species is complicated by their inherent complexity: however, estimation approaches of their key thermochemical quantities are increasingly reliable [16]. In the second article of this issue, by Wang et al. [17], the versatility of malonate dianion as a ligand for the construction of extended networks with different topologies dependent on the coordination geometry of the metal ion was discussed. The synthesis and structure of a novel malonate-bridged copper(II) compound in which copper(II) ions have two different coordination environments in a novel three-dimensional (3D) network was described. Metal malonates have been studied from a
