Peax* for GRAMS

• Instantly search and identify the elements and molecules in the spectra viewed in GRAMS/AI
• Powerful search engine is built with the latest software development platforms available, giving it speed, reliability and optimization

Extensive and Reliable Atomic and Molecular Database

• The Peax element database uses the highly accredited Atomic Spectra Database from the National Institute of Standards and Technology (NIST)
• It provides access to NIST critically evaluated data on atomic energy levels, wavelengths and transition probabilities
• The database contains over 88,000 records
• The molecular database contains over 7200 records from more than 230 of the most common diatomic and triatomic molecules

Line and Band Information

• Line information: atomic number, accuracy, configurations, line references, observed wavelength, ritz wavelength, vacuum wavelength, terms, transition probabilities references, type A_{ki, Ei - Ek, fik, gi - gk, Ji - Jk, log(gf), S}
• Band information: wavelength (vacuum), wavelength (air), molecule, band, intensity, vibrational transition, degrading, transition, source
