Frequency measurements and molecular constants of the (CO2)-C-12-O-16 [10(0)1,02(0)1](11) <- 00(0)0 band near 2.7 mu,m

摘要

Absolute frequencies of 23 transitions ranging from J = 2 to 70 for both the P and R branches of the (CO2)-C-12-O-16 [10(0)1, 02(0)1](11) <- 00(0)0 band near 2.7 mu m are measured to 17 kHz accuracy with sub-Doppler saturated absorption spectroscopy using a precise single frequency PPLN (periodically poled lithium niobate) OPO (optical parametric oscillator). A refined set of molecular constants are obtained which gives the differences between measured and calculated values of less than 7 kHz. (C) 2017 Elsevier Inc. All rights reserved.
