ExoMol line list XXXIV. PH

The line list is designed for studies of exoplanetary and cool stellar atmospheres with temperatures up to 4000K. A combination of empirical and ad initio data are used to produce the line list: potential energy curves (PECs) are fitted using experimental transition frequencies; these transitions are reproduced with a root mean square error of 0.01cm^-1^.

The nuclear Schroedinger is solved using these PECs plus Born-Oppenheimer and spin splitting correction terms. Line intensities and Einstein A coefficients are computed using ab initio Dipole Moment Curves (DMC) X-X and a-a. The resulting LaTY line list, which contains 65055 transitions for 2528 rovibronic states up to 24500cm^-1^ and J=80, is used to simulate spectra in emission and absorption at a range of temperatures.
