1. INTRODUCTION Beams of atoms and molecules are stalwart tools for spectroscopy and
studies of collisional processes. 1− 4 The supersonic expansion technique can create cold …

The motion of neutral molecules in a beam can be manipulated and controlled with
inhomogeneous electric and magnetic fields. Static fields can be used to deflect or focus …

This paper presents a review of the current state of the art in the research field of cold and
ultracold molecules. It serves as an introduction to the focus issue ofNew Journal of Physics …

Collisions of molecules in a thermal gas are difficult to control. Thermal motion randomizes
molecular encounters and diminishes the effects of external radiation or static …

The goal of the present article is to review the major developments that have led to the
current understanding of molecule–field interactions and experimental methods for …

The recent development of a range of new methods for producing samples of gas-phase
molecules that are translationally cold (K) or ultracold (mK) is driving efforts to study reactive …

The motion of neutral molecules in a beam can be manipulated with inhomogeneous
electric and magnetic fields. Static fields can be used to deflect or focus molecules, whereas …

A new line list including positions and absolute transition strengths (in the form of Einstein A
values and oscillator strengths) has been produced for the OH ground X 2 Π state …

A pulsed beam of ground state OH radicals is slowed down using a Stark decelerator and is
subsequently loaded into an electrostatic trap. Characterization of the molecular beam …

Progress on research in the field of molecules at cold and ultracold temperatures is reported
in this review. It covers extensively the experimental methods to produce, detect and …
