摘要

We have recorded extremely weak absorption in the overtone band 5-0 of ~12C~16O X ~1SUM~+ near 0.96 mum with cavity ringdown spectroscopy;the light source was a Raman-shifted dye laser pumped with a frequency-doubled Nd:YAG laser.This band shows lines in branch P to be much more intense than corresponding lines in branch R,in contrast to all lower overtone bands v-0 (v = 1-4).This reversal in relative intensity is explained quantitatively in terms of a radial function for the electric dipolar moment of CO.We have estimated absorption line strengths for P_3-P_18 in band 5-0 of ~12C~16O;these strengths are consistent with a pure vibrational matrix element (5|p(x)|0) - (3.6 ± 0.3) x 10~(-36) C m of the electric dipolar moment p(x),a Herman-Wallis coefficient C_0~5 of about -0.1,and a band strength of (5.1 ± 1.3) x 10~(-29) m at 293 K.
