Spectra of I 4Φ -X 4∆ (0,0) transitions in iron monohydride, FeH

Description

This data set contains ascii files of resolved fluorescence spectra from gas-phase iron monohydride, FeH, following excitation with a single mode continuous-wave laser operating between 507 and 520 nm. Most of the transitions correspond to the I 4Φ -X 4∆ (0,0) transition, which has not yet been reported in the literature. The spectra show some evidence of perturbation in the upper (I 4Φ) state. Data are supplied as starting wavenumber (cm-1) and interval between points, followed by a single column of fluorescence intensities, uncorrected for instrumental response.

Steps to reproduce

31 Raw Fourier transform (FT) resolved fluorescence spectra (in wavenumber, cm-1) are available in this collection. Each file begins with x_start and delta_x wavenumbers in cm-1, followed by a single column of y-amplitude points in resolved fluorescence spectra. The wavenumber x-coordinate has to be generated using the starting wavenumber (cm-1) and the interval between successive points. Filenames. The name for each spectrum is in the form FTS_F#_JUpper#_Date(_2).txt where: F# species the spin orbit component of the upper level. Options include F2 for I^Phi_7/2, and UK when the upper level was part of the newly discovered [20.2]. JUpper#p specifies the upper level's rotational quantum number J, and parity. Date is in the format yymmdd. These spectra are given in their RAW form with calibration supplied by the FT spectrometer. This was refined very slightly by adjusting to known atomic transitions in the spectra. Below are the filenames and the linear calibration we applied to each RAW spectrum.
