摘要: The lowest frequency vibration–rotation band ν 8, corresponding to the degenerate CNC bending vibration of methyl isocyanide (CH3NC) with center at 267.3 cm−1, was studied by FTIR spectroscopy between 215 and 320 cm−1 rotational in range from 201 383 GHz order describe dynamics inclusion all important anharmonic interactions. Assignments extended higher-K states both spectra reveal a resonance crossing v 8 = 2 overtone level due local Fermi resonance. simultaneous analysis types data provides fully quantitative reproduction experimental as well preliminary characterization level. parallel component 524.6 cm−1 assigned for first time region 480 585 cm−1 together hot bands fundamental...
