Abstract
The quantum time evolution in a two-state curve-crossing situation can be computed with the split-operator FFT method. We present an improved version of that scheme, based on the analytic exponentiation of two-by-two matrices. We use this approach to investigate the vibrational dynamics of the coupled b′, c′ 1Σ+u states of the N2 molecule.
