The LPOS spectrum also shows four peaks in the region of the first C–H overtone stretch. From these data, we have determined the fundamental frequencies and anharmonicity constants for the C–H stretching modes, and Acknowledgments We gratefully acknowledge computer time at the Army Research ...
In the first part, a detailed description is given of a specific vibrational model, designed for calculations on the vibrational energy levels in benzene and benzene isotopic species of D6h symmetry. For the description of the C−H stretch system in benzene, a local mode (LM) formalism was...
Photoacoustic Raman spectra of gaseous pyrrole in the 3504-3535 and 3068-3152 cm(-1) energetic windows were measured, to obtain new information about the hot bands in the vicinity of the N-H(ν1) and C-H(ν2) stretch fundamentals, respectively. The observed vibrational patterns are character...
