Peax for GRAMS

Fast search identification of atoms, ions and molecules

Instantly search and identify the elements and molecules of your choice in the spectra you view in GRAMS/AI. The powerful search engine in Peax™ is built with the latest software development platforms available, giving it speed, reliability and optimization.

Automatic peak and band structure finding
Peax™ is using fast and powerful algorithms to easily identify and plot peaks and band structures in your displayed spectrum.

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.

Peax™ is easy to use!

In just a few minutes, you will be searching and identifying spectra like never before in the user-friendly and intuitive interface of Peax™, saving you valuable time and effort.
