NAME: morpholine, 1-oxa-4-azacyclohexane, diethylenimide oxide
FORMULA: C4H9NO
AUTHOR(YEAR): Al Rashidi(2014)
T: 296K
λ: 200-255nm
BIBLIOGRAPHY: M. Al Rashidi, A. El Masri, E. Roth, and A. Chakir, "UV spectra and OH-oxidation kinetics of gaseous phase morpholinic compounds", Atmos. Environ. 88, 261-268 (2014); DOI: 10.1016/j.atmosenv.2014.01.057
COMMENTS: The setup used for the absorption measurements consists of a 30 W deuterium lamp providing a continuum beam extending from 200 to 400 nm.
The issued light is focused onto the entrance of a Jobin Yvon HR 640 spectrometer equipped with a 2400 line mm-1 grating with a dispersion of 0.66 nm -1.
At the exit slit of the monochromator, the light passes through the absorption cell (1.6 m in length and 2 cm in diameter).
The signal is collected by a photomultiplier tube (Hamamatsu R 955) connected to a microcomputer used for data acquisition.
The width of the entrance slit is set to 80 mm yielding a spectral resolution of 0.05 nm.
