The fundamental rotational interval of para-H2+ by MQDT-assisted Rydberg spectroscopy of H2
(2015)The Journal of Chemical PhysicsTransitions from selected nd Rydberg states of H2 to n′p/f Rydberg series converging on the lowest two (N+ = 0 and 2) rotational levels of the X+ 2Σ+g (v+ = 0) ground state of para-H+2 have been measured in the range 1-7.4 THz using a laser-based, pulsed, narrow-band source of submillimeter-wave radiation. The analysis of the spectra by multichannel quantum-defect theory (MQDT) has allowed a complete interpretation of the fine structures ...Journal Article
