Název v původním jazyce

Rotational and rovibrational spectroscopy of the nu(8)=1 and 2 vibrational states of CH(3)NC

Popis výsledku v původním jazyce

The lowest frequency vibration-rotation band nu(8), corresponding to the degenerate CNC bending vibration of methyl isocyanide (CH(3)NC) with band center at 267.3 cm(-1), was studied by FTIR spectroscopy between 215 and 320 cm(-1) and rotational spectroscopy in the range from 201 to 383GHz in order to describe the vibration-rotation dynamics with the inclusion of all important anharmonic and vibration-rotation interactions. Assignments extended to higher-K rotational states in both vibration-rotation and rotational spectra reveal a resonance crossing with the nu(8) = 2 overtone level due to a local anharmonic Fermi resonance. The simultaneous analysis of both types of data provides a fully quantitative reproduction of the experimental data as well as apreliminary characterization of the nu(8) = 2 level. The parallel component of the overtone band 2 nu(0)(8) with band center at 524.6 cm(-1) was assigned for the first time from spectra in the region from 480 to 585 cm(-1) together with
