Superfine and hyperfine structures in the v3 band of 32SF6

摘要: Abstract We present a first detailed account of our theoretical approach to reproduce observed superfine and hyperfine structures in the ν 3 band SF 6 we display various calculated patterns clusters exhibiting effects. The main operators hamiltonian are derived associated constants related molecular parameters. show that, owing off-diagonal terms hamiltonian, mixing occurs between vibration—rotation states with different point-group symmetry species. As consequence, have be considered simultaneously matrices connecting several need diagonalized spectra. analyse greater detail few typical examples from which been determined (e.g. t 044 , c d ). For time, sign is obtained. Also an effective change, Δ found upper lower levels can readily interpreted as manifestation tensor spin—vibration interaction.
