Abstract
The infrared and Raman spectra of KrF2 vapor have been obtained. They clearly indicate a linear and symmetric molecule with the symmetric stretching frequency at 449 cm−1, the asymmetric stretching frequency at 588 cm−1, and the bending frequency at 232.6 cm−1. The force constants are fr=2.46, frr=−0.20, and fα=0.21 mdyn/Å. The negative bond—bond interaction constant can be explained neither by valence bond models nor by a simple molecular orbital model.Keywords
