Schwingungsspektrum von CSFCl Vollständiger Satz von Anharmonizitätskonstanten; harmonische Schwingungsfre- quenzen ; korrigiertes harmonisches inneres Kraftfeld / Vibration Spectrum of CSFCl

Abstract

Abstract The measurement of the infrared spectrum of CSFCl over a large spectral range from 300 cm -1 to 4000 cm -1 was done with a special cell allowing a path-length of up to 20 m. In that way it was possible to obtain a full set of anharmonicity constants by exploring combination and over-tone bands. Hereby the vibration frequencies of the fundamentals could be corrected for anharmonicity. The corrected values of the main species and of a further isotopic species were used to calculate the internal harmonic force field. The harmonic vibration correction terms needed for the determination of the rz-structure turned out to be changed only by 1% as com-pared with those values that were infered from a preliminary force field formerly.
