What does IR spectrum tell you about molecule?

The IR spectra tell you what types of vibrational modes (motion) the molecule responds with after it absorbs that light, and when you figure out which peaks correspond to which motions, you can figure out what functional groups the molecule has and (almost) what the molecule is.

What is phosphonic acid used for?

Phosphonic acids were used for their bioactive properties (drug, pro-drug), for bone targeting, for the design of supramolecular or hybrid materials, for the functionalization of surfaces, for analytical purposes, for medical imaging or as phosphoantigen.

How are phosphonic acid spectra recorded in FTIR?

Each spectrum is the result of 256 co-added interferograms, in the range 4000–800 cm −1. The working temperature in these experiments was 25 °C. The FTIR spectra of phosphonic acid solutions were recorded after filling the ATR cell with 1 × 10 −2 M solutions in the pH range 5–9.

How many interferograms are used for phosphonic acid spectra?

Each spectrum is the result of 256 co-added interferograms, in the range 4000–800 cm −1. The working temperature in these experiments was 25 °C. The FTIR spectra of phosphonic acid solutions were recorded after filling the ATR cell with 1 × 10 −2 M solutions in the pH range 5–9. Double-distilled deionized water was used for background spectra. 3.

Which is the largest library of near infrared spectra?

The near infrared spectral library „IS NIR Spectra“ is a unique collection of 6049 NIR (near infrared) digital spectra. The spectra have been collected in range 4200-10000 cm-1 (=2.4 – 1 micrometers). „IS NIR Spectra“ is the biggest and newest NIR library available on the market.

Which is the fundamental measurement in infrared spectroscopy?

The fundamental measurement obtained in infrared spectroscopy is an infrared spectrum, which is a plot of measured infrared intensity versus wavelength (or frequency) of light. In infrared spectroscopy, units called wavenumbers are normally used to denote different types of light.
