Density Functional Theory |
A theory that is used to describe the electronic ground state properties of matter. It forms the basis of methods in obtaining a solution to the Schrodinger equation for a many-body system, and to investigate the structural, magnetic, and electronic properties of molecules and materials. |

Spectrometry, Mass, Electrospray Ionization |
A mass spectrometry technique used for analysis of nonvolatile compounds such as proteins and macromolecules. The technique involves preparing electrically charged droplets from analyte molecules dissolved in solvent. The electrically charged droplets enter a vacuum chamber where the solvent is evaporated. Evaporation of solvent reduces the droplet size, thereby increasing the coulombic repulsion within the droplet. As the charged droplets get smaller, the excess charge within them causes them to disintegrate and release analyte molecules. The volatilized analyte molecules are then analyzed by mass spectrometry. |
