The Original resRam Lineshape Tool

The public resRam repository is a fork of McCamant-group/resRam. It contains the early command-line optical-lineshape analysis workflow that precedes the newer GUI and Rust implementations in the ResRAM family.

The package accepts four project files: a general input file, dimensionless displacements, vibrational frequencies, and Raman pump frequencies. The documented invocation is:

pip install resram/
resram inp.txt deltas.dat freqs.dat rpumps.dat

The repository describes the implementation as a first-order approximation and records several intended extensions, including higher-order calculations, friendlier harmonic and combination-mode inputs, static-distribution options, and direct Matplotlib output.

That status matters. This is useful scientific lineage and a compact reference implementation, but new work should begin by comparing it with ResRam_NG and resram.rust, which provide more developed interfaces and computation paths.
