Abstract
Synopsis
In some cases of the ion mobility measurements in cooled He gas, we have observed the separation of electronic states for small molecular ions. Both NH+ and ND+ show the separation of X2Π and a4Σ states. The meta-stable
ND
2
+
and
NH
3
+
were observed, but these of
NH
2
+
and
ND
3
+
do not appear in the measurements. The reason of the isotope dependence in mobility measurement is discussed using the calculated potential energy curves for
NH
2
+
and
ND
2
+
.
