Observation of the infrared spectra of the NH2-stretching vibration modes of anilineAr (n = 1, 2) clusters in a supersonic jet using REMPI

Infrared spectroscopy of the phenol-N2 cluster in S and D: Direct evidence of the in-plane structure of the cluster

“…A similar phenomenon has been reported for the NH stretches in aniline-Ar. 11 On the other hand, such a substantial low-frequency shift in phenol-N 2 suggests that the cluster formation with N 2 gives an essential perturbation to the phenolic OH force field. For phenol-N 2 , an in-plane structure has been proposed by Haines et al 5 On the basis of ab initio calculations and intermolecular vibrational analysis, they predicted that phenolic OH is bound to the lone pair of electrons of the nitrogen molecule.…”

Molecular structure and infrared spectra of guanidinium cation

“…In literature the experimental data for more or less similar compounds with NH 2 chemical groups are described. The NH 2 stretching frequencies of aniline and its cation are presented by Nakagana et al [19] For neutral aniline these authors reported two absorption bands at 3508 and 3422 cm −1 and assigned them to as NH 2 and s NH 2 , respectively. According to these data the N H stretching vibrations should be shifted (redshift) by approximately 20-30 cm −1 .…”

Investigation of the hydrated 7-hydroxy-4-methylcoumarin dimer by combined IR/UV spectroscopy

“…In one approach which is also chosen in this paper the ions are generated from the neutral species via UV excitation and successive ionization. [45][46][47][48][49] Among these investigations rearrangement reactions within the ions have been investigated both with ns lasers 51-58 as well as time-resovled studies using ps lasers. [59][60][61] These investigations describe a migration of argon or molecules such as water, methanol, and methane in clusters with small aromatic molecules such as formanilide, 55 acetanilide, 60 4-aminobenzonitrile, 58,61 phenol, 57, 59 aminophenol, 52, 53 benzene, 51 tryptamine, 56 or phenylglcyine.…”
