VPL Molecular Spectra Search Engine

Welcome to the Virtual Planetary Laboratory Molecular Spectra Search Engine!

This is a search engine to query the molecular spectroscopic database HITRAN 2008 and display plots of line intensity versus wavelength (or wavenumber). For further details please see the documentation.

For those who prefer microns:

Display plots for all molecules active in a given wavelength range

Display plots for user selected molecules in a given wavelength range

For those who prefer wavenumbers:

Display plots for all molecules active in a given wavenumber range

Display plots for user selected molecules in a given wavenumber range
