Pendular state spectroscopy in photodissociation experiments of hydrogen-bonded complexes

Large electric fields are being used in our laboratory to orient molecules by brute force. Under the rotationally cold conditions of a molecular beam, the dipole interaction with a static electric field can be made large with respect to the rotational energy such that the molecules orient with this transition moment along the electric field direction. In this paper we will discuss the use of IR laser spectroscopy to probe this orientation and then go on to consider the use of these oriented beams in the study of photodissociation of hydrogen bonded complexes.
