✦ Synopsis

The hfs components of rl Ibeak rotational line of 1271z. assigned as the R(98) line of the 58-I band, are resoIved bq saturated intermodulated fluorescence and a third-derivative technique using a sin$e-mode Ar+-lnser at 5 I15 nm. The spacings betseen different bfs components ze measured bq a heterodlne technique with .m accuracy of 30 kHz. The differences betsecn the upper and lower col;pling constants obtained by J. tit @ins a standard deviation of 15 2 kHz, are: AC& = 1880.198 + 0.09 MHz; AC= 829.20 t 0.01 hHz for the spin-rotation constant; AD = -501.9 2 3 5 LHz for the scalar spixtspin and rf_-l = 356.8 2 1.1 kHz for the tensor spin-spin interaction_ Th& results are compared with data for other vibrational tr.msitions_
