2. Title:
INTERACTION POTENTIAL AND SELECTION RULES IN THE ROTATIONAL SPECTRUM OF WATER MOLECULE DURING ITS COLLISION WITH ATOMS
Authors:
V.K. Konyukhov.



Abstract:
If water molecules are in an atmosphere of buffer monatomic gas, so that the collision frequency with atoms is much higher than the collision frequency between molecules, rotational levels of the molecule with the same angular momentum quantum number j are split into two sets with even and odd quantum numbers m' (projection on the Oz' axis of the molecular coordinate system). Such separation arises due to the interaction of the dipole moment of water molecule with the induced dipole on an atom during particle collision. The symmetry of the molecule−atom interaction potential allows transitions between levels of the same parity, but forbids transitions between sets. Experiments on saturation of rotational transitions in a rarefied gas mixture consisting of heavy water and argon vapors are interpreted. These experiments confirm the assumption that rotational levels of the water molecule are indeed separated into two sets due to the interaction of the molecule with the environment.
