The vibrational assignments and configuration of aniline, aniline-NHD and aniline-ND2
TL;DR: In this article, the Raman spectra (liquid phase) and infrared spectra of aniline, NHD and ND2 were studied, the infrared study being in the 320-3800 cm−1 range for the liquids and solutions and in the 400- 3800 cm − 1 range for vapors.

Rotation‐Vibration Spectra of Methyl Amine and Its Deuterium Derivatives
Allan P. Gray,R. C. Lord +1 more
Abstract: Methyl amine, methyl amine‐d2, methyl‐d3 amine and methyl‐d3 amine‐d2 of high chemical and isotopic purity have been synthesized and their infrared spectra studied at both prism and grating resolution. The rotation‐vibration band centers of methyl amine have been measured with improved accuracy over previous investigations and with the aid of the spectra of the deuterium analogs a vibrational assignment differing in some important respects from those hitherto suggested has been made.The grating spectra in some cases show irregularities in the rotational fine structure but none which can be associated with effects due to hindered internal rotation. Recent studies in the microwave region have shown that these effects should not be observed within the resolution limits of the grating spectrometers used in this work. However, the first overtone of the torsional frequency in methyl amine, methyl amine‐d2 and methyl‐d3 amine has been observed in a position consistent with calculations based on a barrier height ...
