Cold Ion Spectroscopy of Biological Molecules in the Gas Phase
2011The three-dimensional (3D) structures of proteins and peptides in vivo largely determine their biological functions. In vitro these native structures and their heterogeneity reflect a subtle balance between noncovalent intramolecular interactions and those with the surrounding solvent molecules. Decoupling the intra- and intermolecular interactions and

Two-photon induced polarization spectroscopy, TIPS, is demonstrated for the detection of NH3 and CO molecules. Measurements were performed in flow as well as in flame environments. The signal dependence on the laser pulse intensity and on the pump beam polarization was investigated. Two-dimensional signal intensity maps were formed from one-dimensional

We have developed a novel and simple technique to control the temperature and pressure of cold helium gas independently in a designated space above liquid helium. The technique functions through adjustment of both the pumping speed of helium gas and the evaporation of liquid helium using a heater immersed in the liquid helium. This technique enables us

In this chapter, we describe the methods of generating cold neutral and ionic (cation and anion) molecules, their clusters, and metal clusters in the gas-phase. First, a technique of supersonic free-jet or supersonic beam to generate cold neutral molecules and clusters is described.

The field of ultracold matter has developed rapidly over the course of the past twenty to thirty years. One outstanding achievement has been the realisation of Bose-Einstein condensation (BEC) only 23 years ago. Many other fascinating observations of quantum phenomena have been made at an incredibly fast pace using ultracold atomic samples with contact ...
