Comments: Relative quantum yields for the photolysis of NO2 to give NO have been measured at 5 or 10 nm intervals in the 
range of 295 to 445 nm. At all wavelengths shorter than 398 nm the quantum yield is almost constant and independent of NO2 
pressure in the range 0.5-4 torr. At wavelengths longer than 430 nm, there is a small quantum yield for NO formation which 
decreases slowly with increasing wavelength.
