HitranLab is a macOS application for quickly loading HITRAN .par files and exploring line-by-line spectral data. It displays stick spectra and can transform selected transitions into absorbance, transmittance, or percent-transmittance spectra using Gaussian, Lorentzian, or Thompson-Cox-Hastings pseudo-Voigt broadening.

Designed for users familiar with HITRAN, HitranLab provides a simple desktop interface for inspecting molecular line positions, line strengths, isotopologues, and simulated gas-phase spectra without writing code.

One-time price of $1.99
