The nonadiabatic corrections to the vibrational levels of Hz and D2 are evaluated for the X'Z+ state by taking into account the coupling with the E. F t S+clectronic state. The computed corrections diminish ancy between the esperimental and theore%cal vibrational quanta by about 20%.
The pressure coefficient of the vibrational deexcitation of methanol molecules caused by collisions with NH 3, CO 2, SF 6 molecules and He atoms is measured by infrared-far-infrared double-resonance spectroscopy. Large coefficients are measured for those buffer gases which increase the output power
The effect of the internal vibrational motion on the electron difference density has been studied for the hydrogen molecular ion H:. The effect is quite small although there are differences between the static and dynamic densities near the nuclei.
