Abstract

A new room temperature line list for $^{15}$NH$_3$ is presented. This line list comprised of transition frequencies and Einstein coefficients has been generated using the `spectroscopic' potential energy surface NH3-Y2010 and an ab initio dipole moment surface. The $^{15}$NH$_3$ line list is based on the same computational procedure used for the line list for $^{14}$NH$_3$ BYTe reported recently and should be as accurate. Comparisons with experimental frequencies and intensities are presented. The synthetic spectra show excellent agreement with experimental spectra.
