Abstract

Following excitation of the 5d 1Pig Rydberg state of 7Li2 by optical-optical double resonance, fluorescence has been observed in the infrared region to the 2 (1)Sigma+u and C 1Piu states. Analysis of high-resolution Fourier transform spectra yields term energies and rotational constants of the lowest seven vibrational levels of the inner well of the 2 (1)Sigma+u "double minimum" state. The equilibrium term value and dissociation energy have been determined to be Te = 30101.45 +/- 0.12 cm-1 and De = 5621.3 +/- 0.2 cm-1. The v = 0 and 1 levels of the C 1Piu state have been analyzed, resulting in new values of Te = 30551.0 +/- 0.1 cm-1 and De = 7773.3 +/- 0.2 cm-1. Copyright 1998 Academic Press.

摘要

通过光-光双共振激发(^{7}Li_{2})的(5d ^{1}P_{ig})里德堡态后，在红外区域观察到了到(2 ^{1}\Sigma^{+}{u})和(C ^{1}P{iu})态的荧光。对高分辨率傅里叶变换光谱的分析得出了(2 ^{1}\Sigma^{+}{u})“双势阱”态内阱最低七个振动能级的项能量和转动常数。已确定平衡项值和解离能分别为(T{e}=30101.45\pm0.12 cm^{-1})和(D_{e}=5621.3\pm0.2 cm^{-1})。对(C ^{1}P_{iu})态的(v = 0)和(1)能级进行了分析，得出(T_{e}=30551.0\pm0.1 cm^{-1})和(D_{e}=7773.3\pm0.2 cm^{-1})的新值。版权所有1998年学术出版社。
