Laser IR spectroscopy of HeH+ and H+3: new approaches to standard theory and experiment

摘要

The protonited helium molecular ion HeH+ and the hydrogen molecular ion H+3 are investigated by the methods of laser JR spectroscopy in near JR region.The two types of lasers are used in experimental setup for planned experimental investigation of HeH+ and H+3. The two modern theoretical conceptions are applied for the first time for the construction of effective Hamiltonian and effective dipole moments for ions under consideration: the linked ordered schemas of vibrational - rotational interactions and pseudoangular momentum for double degenerated mode of H+3. Nonlinear sequence transformation methods are applicated for analysis of rotational and vibrational dependencies of effective Hamiltonian and effective dipole moments.
