[Absorption line intensities of phosphine in the regions 1 950-2 480 cm(-1) and 3 280-3 580 cm(-1) studied by Fourier-transform spectroscopy].
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 1760 absorption lines intensities of phosphine were obtained, corresponding to five bands in the 1950-2480 cm(-1) region and four bands in the 3 280-3 580 cm(-1) region. The accuracy of the line intensities was estimated to be +/-6%.
