✦ Synopsis

Line shifts of rovibrational levels of the state of the b 'TI, state of Liz caused by rotational coupling to the a 'Xc state have been determined both theoretically and experimentally. Calculated and empirical unshifted term values of the b 'n, state are found to be in excellent agreement. The calculated line shifts show the expected oscillatory structure and agree with the experimental data. Using the shifted b %, energy levels and applying a minor modification to the ab initio a '2: potential curve as indicated by comparison with experimental line widths, theoretical accidental predissociation lifetimes of the Liz A 'Z: state are obtained in almost perfect agreement with the measured values.
