Vapor deposited ethanol–H2O ice mixtures investigated by micro-Raman scattering

Fast detection of paracetamol on a gold nanoparticle–chitosan substrate by SERS

“…6(c), indicating that there are molecules attached on the AuNP-chitosan substrate surface with different orientations. 32,33 The band at 1237 cm À1 for n(CC) and s ip (HOC) is observed in both SERS spectra, appearing as the shoulder in the spectrum in Fig. 6(c).…”

Thermally induced mixing of water dominated interstellar ices

“…The downshift in frequency of the n(OH) band observed during annealing is characteristic of the formation of hydrogen bonds and suggests an interaction between the C 2 68 formed via the mutual diffusion of the ices beyond their respective glass transition temperatures. Certainly, the exact nature of the association between the C 2 H 5 OH and H 2 O layers requires further structural analysis to accurately identify the bonding species.…”

Raman Observation of Silicomolybdic Acid Formation Derived from H₂MoO₄ and Excess Tetraethylorthosilicate Using Hydrothermal Sol-gel Method

“…TEOS is expected to be completely hydrolyzed after refluxing at 80 for 2 h and the received gel contains EtOH, silica-hydrolyzed gel, HCl and molybdates, respectively. Therefore, Raman data of pure EtOH 16) , SMA 8) , the gel after reflux and hydrothermal treatment are summarized in Table 1. Peaks at ~2876, ~2926 and ~2969 cm -1 , which are assigned to other C _ H stretching vibration modes, were nearly unchanged as compared with pure EtOH and the gel.…”
