The first excited C-C-H bending vibration levels in the CaCCH A ˜2⌸ and X ˜2⌺ ϩ states have been rotationally analyzed through cw dye laser excitation spectroscopy of the 4 1 1 band. The upper state is subject to Renner-Teller and spin-orbit splittings. Strong K-type resonance interactions were obse
Cl calculations for the Swan and Fox-Henberg band intenutles III C2 are reported and excellent agreement with euperimental values is found. The X IReI' values vary strongly with bond drstance and in ~ertarn C;IWS az~ found to depend ng-ruticantl~ on the length of the Cl eupmslon.
The present paper reports the derivation of a new theoretical model describing the rotation and vibration of a triatomic molecule. The new method is based on the MORBID (Morse Oscillatory Rigid Bender Internal Dynamics) method (P. Jensen, J. Mol. Spectross: 128, 478-501 (1988): P. Jensen. J. (hcm. S
