✦ Synopsis

We have derived, for M X m Y 3 (C 3v symmetry) molecules which satisfy the conditions of a small ratio of atomic masses m H /m X and of equilibrium angles Y -X -Y close to π/2, simple isotopic relations for rotation-vibration parameters α β λ for the case where one light atom Y (=H) is replaced by a heavier one (=D). The usefulness and predictive power of such relations for the assignment and in the fit were tested by analyzing novel high resolution Fourier transform spectra of the PH 2 D molecule. The region of the three lowest-lying vibrational-rotational bands ν 4 , ν 6 , and ν 3 was studied. The accurate analysis was made possible with the help of recently obtained (O.

Secondary isotope effects were examined in the loss of methyl from the molecular ions of C,D,OC,H, and CD,CH,OC,H, for ion source processes and collisional activation (CA) processes. In the ion source loss of CH, was slightly favored over loss of CD, , but in CA the CH, loss was favored to a much la
