Chemical bonds deviation in NH₃, PH₃, AsH₃, and SbH₃ molecules
Force matrices for PH3, ASH3 and SbH molecules have been computed. Approximation for two anharmonic parameters separately for stretching and bending vibrations is used. Form parameters for the investigated molecules are obtained. X-H bond deviation angles are calculated to be 3.9°, 5.3°, and 5.4°, r...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Force matrices for PH3, ASH3 and SbH molecules have been computed. Approximation for two anharmonic parameters separately for stretching and bending vibrations is used. Form parameters for the investigated molecules are obtained. X-H bond deviation angles are calculated to be 3.9°, 5.3°, and 5.4°, respectively. Negative values for anharmonic parameters are obtained in some cases. This may be caused by deflection of potential energy curve from parabola toward the dependence of higher degree. |
