  2. Internal Coordinate Mechanics - Wikipedia

    en.wikipedia.org/wiki/Internal_Coordinate_Mechanics

    ICM also is a programming environment for various tasks in computational chemistry and computational structural biology, sequence analysis and rational drug design.The original goal was to develop algorithms for energy optimization of several biopolymers with respect to an arbitrary subset of internal coordinates such as bond lengths, bond angles torsion angles and phase angles.

  7. Ion-mobility spectrometry–mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Ion-mobility_spectrometry...

    The first stage of the instrument is an ion source where samples are converted to gas phase ions. Many ionization methods similar to those traditionally used for mass spectrometry have been employed for IM-MS depending on the physical state of the analyte. [9]

  8. Q-Chem - Wikipedia

    en.wikipedia.org/wiki/Q-Chem

    Q-Chem software is maintained and distributed by Q-Chem, Inc., [6] located in Pleasanton, California, USA. It was founded in 1993 as a result of disagreements within the Gaussian company that led to the departure (and subsequent "banning") of John Pople and a number of his students and postdocs (see Gaussian License Controversy [7]).

  9. Molecular mechanics - Wikipedia

    en.wikipedia.org/wiki/Molecular_mechanics

    A force field is used to minimize the bond stretching energy of this ethane molecule.. Molecular mechanics uses classical mechanics to model molecular systems. The Born–Oppenheimer approximation is assumed valid and the potential energy of all systems is calculated as a function of the nuclear coordinates using force fields.
