Abstract：The data of line intensities of the fundamental and low overtone absorption bands of phosphine are the basic reference data for the applications in quantative analysis and astronomy.The method of high-resolution Fourier-transform spectroscopy study on the absorption line intensities is discussed.With a series of measurement and fitting the line profiles, altogether 1 760 absorption lines intensities of phosphine were obtained, corresponding to five bands in the 1 950-2 480 cm-1region and four bands in the 3 280-3 580cm-1 region.The accuracy of the line intensities was estimated to be ±6%.
