C. Meißner, J. I. Hölzer and T. Seeger, “Determination of N2-N2 and N2-O2 S-branch Raman linewidths using time-resolved picosecond pure rotational coherent anti-Stokes Raman scattering”, Appl. Opt. 58, C47 (2019)
Source record · Catalogue · Review register
DOI: 10.1364/AO.58.000C47
Source kind: measurement
Recorded technique: Picosecond time-resolved dual-broadband pure rotational CARS (pp. 2-3): a frequency-doubled Nd:YAG probe (532 nm, about 1 cm-1, 100 ps) delayed up to 700 ps against broadband DCM dye pump and Stokes (626 nm, about 460 cm-1), planar BOXCARS, in an electrically heated furnace at 295-1900 K and ambient pressure, in pure N2 and in air; 500-shot averages per delay. Each S(J’’) time trace fitted with a monoexponential decay from 230 to 667 ps (after the nonresonant signal has vanished); the width follows from Eq. (1).

Curation notes#
Identity checked against the first page (Appl. Opt. 58(12), C47-C54, 2019). Page numbers are pdf pages 1-7. Material: 14N2, S-branch lines labelled by the lower level J’’. No isotopologue is measured.
WIDTH CONVENTION. FULL widths: p. 2, ‘the Raman Lorentzian linewidth Gamma_J’’ [full width at half-maximum (FWHM)] is given by Gamma_J’’ = (2 pi c tau_CARS,J’’)^-1’ (Eq. (1)), tau the decay constant of the CARS signal; table heads ‘Gamma_J’’(FWHM)’. UNIT: the heads print ‘/10^-3 cm’ (images checked), where cm-1 is meant (Eq. (1) gives a wavenumber): recorded as unit cm-1, scale 1e-3. PRESSURE: these are WIDTHS at the measurement pressure, not coefficients per atm: the heads carry no pressure unit and the measurements were ‘at ambient pressure’ (pp. 3 and 7), the pressure not given numerically; the same group’s holzer_2021 divides by the pressure and prints per atm. Recorded with parameters.pressure = “ambient, not stated numerically” and no state: how to use them must be decided at review (about 1 atm; the N2 values at 295 K are about 14 % below herring_1986’s per-amagat coefficients converted to 1 atm).
UNCERTAINTIES: ‘The standard deviation was determined from the 95% confidence intervals of the fitting process’ (pp. 4 and 6): a fit standard deviation (recorded as 1 sigma; statistical only).
TABLE 2 is N2 IN AIR. The paper calls these ‘N2-O2 S-branch Raman linewidths’ but they are measured ‘in air’ (‘The resulting N2-O2 S-branch Raman linewidths for the gas mixture air’, p. 4; air ‘basically considered a mixture of N2 (79%) and O2 (21%)’); no separation of the O2 contribution by a mixing rule is made. Recorded with perturber = “air”. J’’ lines coinciding with O2 lines are excluded (blank). They are up to 29 % below Table 1’s, most at low J’’ (p. 4).
As printed, some values stand out from their neighbours (not errata; images checked): Table 1 295 K J’’ = 23 36.7 (22: 48.1, 24: 40.4); 870 K J’’ = 33 17.7; 1650 K J’’ = 6 49.6 and J’’ = 9 39.4; Table 2 at 1900 K lies above 1650 K throughout. The O2 lines in air could not be fitted monoexponentially (quantum beats, Fig. 9): no O2 widths here (holzer_2021 gives them).
Comparisons (figures only, not extracted): Kliewer et al. 2012 (Ref. 13) and Miller et al. 2011 (Ref. 16) S-branch N2 widths; Fanjoux et al. 1996 (Ref. 33) and Rahn and Palmer 1986 (Ref. 8) Q-branch widths at 295 K (Figs. 5, 8).
Recorded bibliographic identity status: VALIDATED_WITH_WARNINGS. This concerns identification of the source; it does not establish the scientific correctness of its contents.
