Estimate of P-and P,T-odd effects in diatomic van der Waals molecules

The magnitudes of the possible P-and P, T-odd effects in diatomic van der Waals molecules are estimated. The estimates fall between the values corresponding to atoms and molecules/radicals. Arguments are presented showing that the loss of approximately two orders of magnitude in the strength of the effect for van der Waals molecules with an unpaired electron, such as CsXe, as compared with molecules/radicals can be partially compensated by a number of experimental advantages of working with van der Waals molecules.
