Isotopomer-selective overtone spectroscopy by ionization detected IR+UV double resonance of jet-cooled aniline

Stereomutation dynamics in hydrogen peroxide

“…9 and 8 show the RPH model to be excellent for this example, and Table 1 suggests that it is of similar quality for other excitations in H 2 O 2 . This is excellent news for treating multidimensional tunneling in molecules similar to H 2 O 2 but possibly also much more complex systems such as Aniline (and its isotopomers, in particular the chiral isotopomers C 6 H 5 NHD), where we have already applied the approach to spectroscopic results from our work [74,95].

High resolution rovibrational spectroscopy of pyrimidine: Analysis of the B1 modes ν10b and ν4 and B2 mode ν6b

“…Only a few aromatic compounds including the benzene molecule and its isotopomers [20,21] have been investigated in high resolution by FTIR [20][21][22][23][24][25] and diode laser spectroscopy [26,27], so far. We have initiated a project to systematically record and analyze the FTIR spectra of the aromatic compounds fluoro- [28] and chlorobenzene [29], phenol, aniline (see also [30][31][32]) and benzaldehyde and the heterocyclic aromatic compounds pyridine [33,34] and pyrimidine [35]. The subject of the present paper is the detailed rovibrational analysis of pyrimidine in the region 600-900 cm À1 .…”

The NH and ND stretching fundamentals of 14NH2D

“…In a second paper we deal with the bending fundamentals of 14 NH 2 D and 14 ND 2 H [2]. The hindered inversion at the pyramidal nitrogen atom is among the classic problems in intramolecular dynamics and in particular tunneling dynamics including the possibility of molecular chirality with appropriate substitution [3][4][5][6]. Ammonia and its isotopomers have been prototype molecules for the study of inversion at the pyramidally substituted nitrogen atom for many years [3,[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”
