BS>transitions J = 4 yields 5 and J =5 yields 6 for the two isotopic species I/sup 127/Br/sup 79/ and l/sup 127/Br/sup 81/ was invest igated. The spectrum obtained could be well explained on the basis of the theory given by Bardeen and Townes. The necessary secular equations were developed and solved and the frequencies of the lines correspending to the expected transitions were calculated. The agreement between the calculated and the observed frequencies is satisfactory. The analysis of the spectrum yields the following molecular and nuclear parameters: B/sub e/(IBr/sup 79/) = l682.22 plus or minus 0.1 Mc/sec. B/sub e/(IBr/sup 81/) alpha /sub e/(IBr/sup 81/ = 10.26 plus or minus 0.1 Mc/ sec, (eQq)/sub Br7//sub 9/= 722 plus or minus 15 Mc/sec, (eQq)/sub Br8//sub 1/ = 603 plus or minus 15 Mc/sec, and (eQq)/sub I12//sub 7/ = 2 731 plus or minus 60 Mc/sec. The two different values of B/sub e/ for IBr/sup 79/ and IBr/sup 81/ yield a bond distance in IBr = 2.485 A. (auth)
