✦ Synopsis

A re-investigation of NH3 in the vicinity of the fi state origin by 2 + 1 multiphoton ionization photoelectron spectroscopy (MPI PES) has revealed the presence of a previously unreported combination band of the c' state which involves the Y, symmetric stretch and the Y, umbrella mode. The symmetric stretch frequency ofthe c' state and of the ground state ion have been measured.

What was once thought to be an anomalous 2 + 1 MPI PES of the NH, d state origin is now re-assigned to the I?' 1 '23 level.
