Comments: The absorption coefficient of N2O5 has been measured over the wavelength range 3800-2850A. The value rises steadily 
from approximately 0.002 at the first wavelength to approximately 0.52 at 2850A. The absorption coefficient curve continues to rise 
to shorter wavelengths and qualitative observations indicated no maximum as far as 2400A. No absorption which could be attributed 
to N2O5 could be observed in the 4500A region.
