ChemInform Abstract: ELEMENTARY RECONSTITUTION OF THE WATER SPLITTING LIGHT REACTION IN PHOTOSYNTHESIS. 2. OPTICAL DOUBLE RESONANCE STUDY OF (CHL A.2H2O)N TWO-PHOTON N INTERACTIONS IN NONPOLAR SOLUTIONS

First investigations of the [Formula: see text] system of Na3 at rotational resolution are reported. Using resonant two-photon ionization and optical-optical double resonance spectroscopy, two vibronic bands were assigned and rotationally analyzed. In the B state, the three sodium nuclei perform a nearly free pseudorotational motion in the moat of a pseudo-Jahn–Teller potential that is characterized by a vibronic angular momentum quantum number j. In states with J > 0, each rotational level is split by Coriolis interaction. Rotational and Coriolis coupling parameters were determined and are discussed in terms of the dynamics of the vibronic coupling in this floppy molecule.

Pair State

The D(0u+) ion-pair state of I2 has been analyzed by the optical–optical double resonance (OODR) technique. In a stepwise three-photon excitation scheme, D(0u+)–B3Π(0u+)–X1Σg+, the D(0u+) state appeared in the OODR spectrum as the vibrational progressions consisting of O, Q and S branches in accord with the rotational selection rule of ΔJ = 0 and ±2 for the coherent two-photon transition from the B3Π(0u+) state. The D(0u+)–X1Σg+ fluorescence was resolved to determine the absolute vibrational numbering of the D(0u+) state. We derived Dunham parameters effective for ν = 0 through ν = 124 which were used to construct a Rydberg–Klein–Rees (RKR) potential curve.
