Frequently asked questions

What is the spectral resolution achieved in this study?

The instrument-limited spectral resolution was determined to be better than 0.06 cm-1 for each transition.

How long did it take to collect the spectra?

Spectra were collected with just 4 scans, which correlates to a 40 second collection time.

What is the wavelength accuracy of the spectrometer?

The wavelength accuracy was determined to be better than 0.001 cm-1 against reference values.
