“…The cross-section for the 16 1, 16 ‹ 16 0, 16 F 1 line between HO 2 and water is estimated to be 224 ± 137 Å 2 , which is larger than the cross-section between HO 2 and N 2 estimated to be 120 ± 15 Å 2 . Barry et al [16] have measured the pressure-broadening coefficients of 2m 5 band of formaldehyde with various collision partners. The estimated cross-section between formaldehyde with water to be 381.2 ± 10.4 Å 2 and that with N 2 to be 134.6 ± 3.5 Å 2 .…”

Buffer-gas pressure broadening for the (0003)←(0000) band of N2O measured with continuous-wave cavity ring-down spectroscopy

“…Barry et al [31] measured broadening coefficients for the 2m 5 band of CH 2 O and firstly adapted the Permenter-Seaver's model for pressure broadening to estimate the binding energy of (CH 2 O) 2 . Permenter and Seaver [32,33] have developed a successful model that correlates Boltzmann averaged cross-sections, r M , of a variety of energy transfer processes for a variety of collision partners, M, with the intermolecular well depths, e AM , for the interaction between the molecule, A, and a collision partner, M.…”

Understanding the sensitivity of cavity-enhanced absorption spectroscopy: pathlength enhancement versus noise suppression

“…(I 0 -I) and determine how it varies with R. A different equation has to be used to account for this ''unsymmetrical'' transmission of light through each mirror and is given in Eq. (25) in the following section. With ad set as 1 9 10 -7 and T = (1 -R), the resulting plot is shown in Fig.…”

“…[5]). Since its advent, CEAS has found numerous applications in detecting trace species [5][6][7][8][9][10][11][12][13][14][15], studies of gas phase kinetics [16][17][18][19][20][21], capturing weak molecular transitions [22][23][24][25][26] and probing interfacial interactions [27][28][29] and molecular dynamics [30].…”
