Abstract :
The N 1s→π* photoabsorption profile of N2 is quantitatively analysed. New spectroscopical constants for the N 1s−1π* core-excited state are determined from NEXAFS spectra and compared to previously published data. The accuracy of the new spectroscopical constants is discussed and error bars are given for the present data analysis. The goodness of the new spectroscopical constants is demonstrated by lifetime vibrational interference (LVI) simulations of the resonant Auger decay from the N 1s−1π* core-excited state to the A2Πu singly ionized final state of N2. These new values give a much better agreement with recently obtained experimental data compared to the previously published ones.
