Explore Over 500 Gas-Phase Infrared Spectra

IRVaporWare for macOS and iPad

Quantitative Spectra, Interactive Exploration

• Explore over 500 gas-phase infrared spectra.

• Work with quantitative spectra normalized to 1 ppm·m at 296 K.

• Examine spectra acquired at a resolution of 0.12 cm⁻¹.

• Select a chemical from the menu or search by CAS number.

• Apply Gaussian broadening to explore spectra at lower resolution.

• Inspect spectral position and absorbance or transmittance with an interactive cursor.

• Adjust concentration and path length to explore their effects on the spectrum.

• Export spectral position and absorbance or transmittance as two-column data for further analysis on macOS.

Select a chemical, explore its quantitative infrared spectrum, and adjust concentration and path length to see how absorption changes. Apply Gaussian broadening and inspect spectral features with an interactive cursor.
