title: Optical-Optical Double Resonance Spectroscopy of the H1(u)((3)P(1))-A(3)Pi(1u)-X(1)Sigma(+)(g) Transition of I(2).
abstract: 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 + 2) photoexcitation sequence using the A(3)Pi(1u) state as an intermediate. The molecular parameters were obtained from data for 0 </= v </= 9 and 6 </= J </= 135 and used to construct an RKR potential function. We predict the location of unknown h0(-)(u)((3)P(1)) state in discussing the Omega-doubling of the H1(u)((3)P(1)) state under the pure precession approximation. Copyright 2000 Academic Press.
