| Abstract: | D ← X resonance enhanced three-photon excitation spectrum of iodine was observed by a cw intracavity absorption technique. Vibrational quantum numbers of D ← X transitions are given for every major spectral feature. The corresponding one-photon enhancement from the B state is evident from the one-photon vibrational assignment. The spectroscopic constants for the D state are v00 = 40 998 cm?1 ω′0 = 113 cm?1 and ω′0χ′0 = 0.045 cm?. |
