Two recent detailed models of multiple-photon excitation in SF6 are compared. By performing equivalent vibration—rotation calculations using the two different basis sets, we have found that the results are in complete agreement. Rotational effects in both cases completely overshadow the vibrational structure, making a triply degenerate anharmonic oscillator model sufficient for describing multiple-photon excitation in SF6.
