What is the definition of absorbance if there is some absorption, some reflection, and some transmission? The author's answer: You may in principle define it such that it describes the decay of intensity only due to absorption. However, the term is not usually used in such a situation. Her...
Having determined the classical transmittance in the Ch2 channel, the partial pressure of water vapor (PRSH2O) can be determined based on the relationship between transmittance, absorbance and pressure: PRSH2O≈−0.00854Log(TR2)mbar . (6) We calculated the conversion factor depending on light pa...
A quadratic formula that accurately represents general absorptance is both developed for 5 cm(-1) data on the 4upsilon(2) + upsilon(3) band of CO(2) centered at 4853.58 cm(-1) and generalized to a polynomial function of the weak- and strong-line limits of known models. DOI: 10.1364/...
FIG. 13 shows an exemplary plot of the absorbance spectra of a hybrid photochromic/electrochromic switching material according to Formulation #2, comprising compound S054. Faded state (solid line); darkened using a 365 nm light source without (open circle) or with (open square) EnergyFilm™;...
x(λ) is the absorbance of the film, as the subscripts “f”, “s” and “a” refer to the film, the substrate and the air, respectively. It was assumed in the derivation of Equation (1) that the film thickness d has a continuous uniform distribution in the interval [d d¯ −...
UV-VIS-IR spectroscopy is a well-established technique for the identification of the coloring agents (chromophores) in stained glass windows, whereby the specific absorbance peaks in the spectra can be analyzed and interpreted [2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22...

The AUP for road marking paint should have good optical clarity to ensure the effective absorbance and high reflection of road paint bead. Figure 5 shows the UV-visible spectra of the AUP series with different t-AU contents. The transmittance values of most AUPs were more than 90%, showing...
