Molecular Beam Apparatus with a Spray-Jet Technique: Formation |
|
Abstract: We developed a molecular beam apparatus with a spray-jet technique that enables us to produce a molecular beam of neutral non-volatile molecules from a sprayed mist of a sample solution. Using the apparatus in combination with pulsed lasers provides insight into the electronic states of neutral non-volatile solute molecules as well as the interaction between different neutral non-volatile solute molecules and the interaction between neutral non-volatile solute and solvent molecules. In this paper, we briefly review the spray-jet technique and report on the formation of molecular clusters composed of solute molecules (1,5-dihydroxy naphthalene) and solvent molecules (acetone, methanol, and water).
