✦ Synopsis

We describe the results of optical-optical double-resonance spectroscopy of Cl2 on the 1,(3Pt)+-(hvl)-A%( 1,) + (hu, )-X 'Zi transition. The state-selective transition from the ground state of Cl2 to the A 'lI( I,) state was observed by scanning the pump laser ( hu, ) frequency, while furing the probe laser frequency ( hv2) to the ID ( "P2)-A alI ( 1.) system. In this procedure, a rotational analysis on the A 'IT( 1 U 1-X 'I;: system is made on several vibrational bands for two isotopic species, '5C135CI and 37C135C1, and the vibrational numbering is determined from the isotope difference. The l,( 'P2)-A 'II( 1.) system is also analyzed fo establish the absolute position of the l,("Pz) ion-pair state.

Optical-optical double resonance spectroscopy was used to study the 1 g ( 3 P 1 ) ion-pair state of I 2 correlating to I -( 1 S) + I + ( 3 P 1 ) at the dissociation limit. We gained access to the 1 g ( 3 P 1 ) state though the A 3 (1 u ) state in the (1 + 1) photon-excitation scheme. The pump laser

We report the analysis of the H1 u ( 3 P 1 ) state of I 2 by optical-optical double resonance. This state lies in the second tier of ion-pair states and its observation was achieved by using the (1 ϩ 2) photoexcitation sequence using the A 3 ⌸ 1u state as an intermediate.

Polarization labelling spectroscopy is applied to study excited states of K2 lying in the energy range 23800-25800 cm-' above the bottom of the ground state. The two observed states are identified as 3 'l&(4 'S+S 'P) and 3 '&/ (4 \*S+ 3 'D). Molecular constants are derived for both states from a Dun
