Hyperfine structure of the rovibronic transitions R(0)–R(10) and P(1)–P(5) in the 13–1 band belonging to the B–X system of 127I2 was studied by rectangular-crossing molecular-beam laser spectroscopy. The full width at halfmaximum of the observed lines was 5 MHz, which corresponds to a resolving power of 108. Not only allowed transitions δF = δJ but forbidden transitions δF = 0 and δF =−δJ were identified, and absolute hyperfine coupling constants of the rovibronic states (J = 0−10) in the B(v′ = 13)–X(v″ = 1) transition were determined. In addition, the relative line strength of each hyperfine transition was compared with the theoretical value.
