Hyperfine structure of higher rovibrational levels in the iodine B state studied by Ar+ laser induced fluorescence

Résumé

The hyperfine structure of higher rovibrational levels in the iodine B state has been investigated by studying the fluor-escence of a well collimated iodine molecular beam excited by the 5017A AI+ laser line. Nine transitions: R(13) 61-0, P(12)61-0, R(49) 67-0, R(39)64-0, R(26)62-0, P(56)73-0, R(54)70-0, R(55)77-1, R(51)6W were identified and their center of gravity located to an accuracy of kO.001 cm-'. A fit of the theoretically predicted hyperfine patterns to the ob-served spectra enables one to study the variation of the magnetic hyperfine constant C' with the vibrational quantum num-ber U' in the range 61 Q U' < 73. The observed behavior is well accounted for by a simple theoretical model developed by Vigu6 et al.
