Title: INTERMOLECULAR POTENTIAL OF EXCITED ATOMS AND MOLECULES FROM MATRIX SHIFTS.
Creators: Roncin, J.- Y.
Issue Date: 1969
Abstract: The experimental shifts and broadening of far u.v. transitions of trapped species have so far permitted only qualitative conclusions concerning the dimensions of the excited $states.^{1}$ In particular the matrix isolation technique has strikingly shown the profound difference in behavior of trapped molecules according to the nature of the transition; valence transitions are little affected whereas Rydberg transitions are strongly $perturbed.^{1, 2}$ Enough experimental data are now available to attempt a quantitative estimation of the dimension of some excited states on the basis of a simple Lennard-Jones intermolecular potential $V = re[(\frac{\sigma}{r})^{12} - (\frac{\sigma}{r})^{6}]$. The values of $\sigma$ and $\epsilon_{i}$, computed for some excited states of Xe, Kr, Hg, CO, NO and $N_{2}O$, are given below: [FIGURE] During the year 1969, J.-Y.
