Part of the Springer Theses book series (Springer Theses)

Abstract

Quantum state-specific preparation and alignment of a molecular beam of methane are two central concepts in this thesis work. In this chapter, I explain the processes by which the molecules in the molecular beam are rovibrationally excited and aligned. Experimental evidence of the extent of state-specific preparation is shown.
