Analysis of High-Resolution FTIR Spectrum of the ν6Band of H13COOH

FTIR spectra of the ν6 and ν8 bands of 13C formic acid molecule—Assignment of FIR-laser lines

“…[5] and in addition the interaction parameters for the main isotopic species [11] are given for comparison in Table 2. It should be noted that the ground state parameters were also varied to achieve a better quality of the fit.…”

“…The only work dealing with this subject was that by Ong with coauthors [5] published in 1999. They assigned 3004 FTIR transitions in the m 6 band but were not able to detect the m 8 band because of it's weakness.…”

“…It is obvious that transitions in the m 8 band using the parameters derived in Ref. [5] could be calculated with much worse uncertainty. The identification of the laser lines in Refs.…”

Helium Nanodroplet Isolation Spectroscopy in an Undergraduate Teaching Laboratory

“…For H 13 COOH in the C-O stretching band, these are very accurately known. 19 After establishing suitable parameters for collecting the spectrum (scan range, scan speed, data acquisition rate, lock-in sensitivity…), students begin scanning and acquiring data. While we have LabVIEW programs that fully automate the scanning, it more engaging to manually control the coarse stepping of the laser (while a separate program applies a triangle wave to the piezo element for the fine scanning).…”

FTIR and millimeter wave investigation of the 71 and 91 states of formic acid HCOOH and H13COOH

“…Of the fundamentals of the 13 C species only the m 6 band has previously been investigated with high resolution [8]. Therefore, the primary goal of the present paper was to measure and analyze the high resolution FTIR spectrum of the m 7 /m 9 fundamental band system of H 13 COOH.…”
