✦ Synopsis
The diatomic species CuI and AgI were produced by the reaction of metal atoms, formed in situ by ablation of an appropriate metal rod, with methyl iodide entrained in argon. The rotational spectra of the MI species so produced were then observed with the aid of a pulsed-jet, Fourier-transform microwave spectrometer. The ground-state rotational constant B 0 , centrifugal distortion constant D 0 , iodine nuclear quadrupole coupling constant c(I) and iodine spin-rotation coupling constant M bb (I) were determined with high precision for each of the isotopomers 107 Ag 127 I, 109 Ag 127 I, 63 Cu 127 I and 65 Cu 127 I by analysis of its rotational spectrum. In the case of the two CuI isotopomers, the nuclear hyperfine coupling constants c( 63 Cu), c( 65 Cu), M bb ( 63 Cu) and M bb ( 65 Cu) were also established.
