摘要

Molecular spectroscopy is a branch of physics which deals with the interaction of electromagnetic radiation with matter.Using the new theoretical approach,i.e.,Lie algebraic approach,we calculate the infrared spectra of phosphine in the range from 3000cm-1 to 9500cm-1 and nitrogen trifluoride in the range from 900cm-1 to 4500 cm-1.The model Hamiltonian constructed seems to describe the P-H and N-F stretching modes accurately with only four numbers of parameters.The present calculation not only predicts the higher overtones but also shows good agreement with the few observed data.
