Accurate Calculation of the Infrared Spectra of HD+, HT+, and DT+

Abstract

Certain transition frequencies in the vibrational-rotational spectra of H${\mathrm{D}}^{+}$, H${\mathrm{T}}^{+}$, and D${\mathrm{T}}^{+}$ have been calculated to a high degree of accuracy. For H${\mathrm{D}}^{+}$ the differences between the calculated frequencies and the recently reported observed frequencies are less than those previously obtained and are within the error bounds of the computation.
