We also present results from in vivo studies in which we find that whilst the 820 nm feature is measured with lower accuracy for a given light flux than the 975 nm feature, it is intrinsically a more accurate differential path estimator. or This site needs JavaScript to work properly.

Water vapor absorption in the visible and near infrared: ... to determine aerosol size spectra, found that the aerosol optical depth must be computed with a standard de- viation of <7% to obtain reliable size distributions. 38(7) 1216-1223 (1999), L. F. H. Bovey You may subscribe either as an OSA member, or as an authorized user of your institution. J. Opt. Article copyright remains as specified within the article. Water associates strongly with ions, organic monomers and polymers by hydrogen bonds; therefore, water absorption bands in the near infrared spectrum are influenced by effects of solutes in water. Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. A curve is included which shows five prominent absorption bands at 0.76, 0.97, 1.19, 1.45, and 1.94μ; and a table gives experimental results of water absorption at 20°C. You don't need spacers.
