SpectraMatcher is a fast, GUI-based, interactive Python program for comparing computed and experimental vibronic spectra. It features real-time spectral adjustment, automated peak assignment, type-specific anharmonic corrections, and export to publication-ready formats. Supports Gaussian log files and plain text or spreadsheet experimental spectra.

Python package which provides an implementation of a PIMC method that calculates thermodynamic properties of quantum mechanical systems described by vibronic models
