Hydrogen Cyanide H(13)C(14)N Absorption Reference for 1530 nm to 1560 nm211 Wavelength Calibration-SRM-2519. Standard Reference Materials

摘要

Standard Reference Material (SRM) 2519 is an optical-fiber-coupled abosption cell211u001econtaining hydrogen cyanide (H13C14N) gas. It is intended for use in calibrating 211u001ethe wavelength scale of wavelength measuring instruments in the 1500 nm region. 211u001eAbout 50 accurately measured absorption lines of the R and P branch of the 211u001e2(nu(sub 3)) rotational-vibrational band of H13C14N are located in the 1530-1560 211u001enm region. The authors have measured the line centers and pressure-induced shifts 211u001eof 21 lines and certify their wavelengths with an expanded uncertainty (coverage
