C.W. Optical–Optical Double Resonance in /2: Hyperfine Structure in the E 0−g+– B 0u+ System
Keyword(s):
Hyperfine structure for several E(0g+)–B(0u+) rovibrational transitions has been measured for the first time. Two single frequency lasers were used to excite E(0g+)(υ*, J*)–B(0u+)(υ′, J′) – X(1Σg+)(υʺ, Jʺ) transitions which result in Doppler-free E(0g+)(υ*, J*)–B(0u+)(υ′, J′) fluorescence excitation spectra. Hyperfine parameters are obtained for E(0g+)υ = 11 (eQq = +483±4 MHz, C = –210±3 kHz) and E(0g+)υ = 8 (eQq = +492.3±2.5 MHz, C = –205±3 kHz). The non-zero C constant is shown to arise from mixing with a nearby 1g state and the eQq constant shows the 3P2(I+) origin of the E(0g+) state.
