Vibrational Frequency Shifts In Dense Molecular Fluids, Richard Alan Lesar
Vibrational Frequency Shifts In Dense Molecular Fluids, Richard Alan Lesar
Richard Alan Lesar
A theory is presented for calculating the bond length and vibrational frequency shifts in dense molecular fluids. We combine equation‐of‐state calculations based on the effective spherical potentials of Shaw, Johnson, and co‐workers with a simple model for the interactions of a molecule with the surrounding fluid. The repulsive interactions are approximated with the hard‐sphere model of Schweizer and Chandler. We extend their model by including an improved treatment of the long‐range attractive interactions and the centrifugal forces. We apply this model to fluid nitrogen and compare with static and shock wave experimental frequency shifts, as well as computer simulation data, …

Retrospective Theses and Dissertations
Advances in simulation methodology, and the computer support systems to implement these methodologies, have led to the development of integrated simulation support environments. These environments, or collection of software tools, seek to aid the analyst in developing models, data management and analysis, and data presentation.
While an integrated simulation environment provides a more organized structure for managing and performing simulation projects, and provides a database management structure for storing, manipulating, and analyzing data, they do not address the actual process of going out and obtaining the data. As a result, many of the common problems associated with poor problem and …
