Rotational contours of the (2+ 1) REMPI spectra of iodine due to resonance excitation to the [ ZlIs,z]c5d; lg Rydberg state have been recorded at room temperature. Rotational parameters, &, were estimated from the band-head structure and used to derive the band origin by spectral simulations. T.= 59
Using two-step laser excitation, a new ion-pair state of I1 was observed It has been assgned lo O+ and should correlate to the iontc alomic states 3Po(1> and '&,(l-) The molecular pnrametcrs are Tc = 47024 6(25) cm -4 = , we 104.2(10) cm-', and Be = 0\_02lOO(RO) cm-l
We have reexamined the sequential two-photon absorption of I 2 from the X 1 + g ground state to the lowest D 2 g ( 3 P 2 ) ionpair state using the high vibrational level of the B 3 (0 + u ) state as an intermediate. The double resonance transition to the D 2 g ( 3 P 2 ) state was found to occur thro
