DepolTools
- an OpenSource software package

Evaluation Method for Raman Depolarization Measurements including Geometrical Effects and Polarization Aberrations

Introduction

This programme addresses the notoriously difficult problem to quantitatively link measured Raman depolarization values to theoretical polarizability tensor quantities, since quantum calculations do not incorporate experimental parameters. A numerical model is programme to calculate, for realistic experimental configurations, effective Raman line strength functions, which find their way into depolarization ratios. The model is based on interlinked integrations over the angles in the light collection path, and a finite Raman source volume along the excitation laser beam. The model deals as well with the conditional aperture parameters, associated with more than one optical component in the light collection path. Finally, the model also takes into account polarization aberrations introduced by the sample cell windows.

Application & Classes

The Depol-Tools are written in C++ and use parts of the libraries from "ROOT - A Data Analysis Framework" This is framework was predominantly developed for the use under Linux. The compilation on Windows is not recommended not straight forward, thus no Windows version is supported.
