PAH Single-Photon Basis Spectra for Arbitrary Radiation Fields

Helena Richie and Hensley (2025) developed these basis spectra data files to facilitate the generation of Polycyclic Aromatic Hydrocarbon (PAH) emission spectra. The data enables the calculation of spectra and band ratios for arbitrary radiation fields using the single photon approximation method.

Use Cases

• Generating synthetic PAH emission spectra by applying basis spectra to arbitrary radiation field inputs
• Calculating PAH band ratios to analyze the physical state of the interstellar medium
• Benchmarking astronomical observations against theoretical single-photon approximation models

Strengths

• Implements the Richie & Hensley (2025) single photon approximation model
• Supports arbitrary radiation field configurations
• Provides basis spectra for band ratio calculations

Limitations

• Lack of explicit column definitions or file format documentation
• Restricted to the single photon approximation framework
• No sample data available for preliminary verification
