✦ Synopsis
We report the discovery of high-lying, very-lung-lived Rydberg states in NO. With that we were able to determine the ionization potential of NO to be 74721.7 & 0.4 cm-'. The existence ofthese States explains a discrepancy between the values for the ionizatlon energy of NO from "zero kinetic energy photoelectron spectroscopy" and Rydbcrg f-series extrapolations. Now these values are in perfect agreement. Hence we propose a general method for the direct measurement of highly accurate ionization potentials.

Variation of the reaction mechanism for homogeneous thermal decomposition of NO into N 2 a n d O2 in the temperature range between 1000 and 4000 K is studied. The decomposition always proceeds through an atomic chain mechanism initiated by formation of oxygen atom. However the step of the oxygen ato
Dedicated to Professor Dr G. Spiteller on the occasion of his 60th birthday It is shown that the position of the double bond close to the hydrocarbon end of an aliphatic diene functionalized at C(1) can readily be determined by chemical ionization with N O ' . Owing to the low abundance of the ions
