The Absorption Coefficient of Nitrogen Pentoxide in the Ultraviolet and the Visible Absorption Spectrum of NO3

摘要: Absorption spectrograms have been made of the gaseous system N2O5–O3 during decomposition ozone and into subsequent N2O5, placing these in time such that one was taken when consisted essentially only N2O5 oxygen. From as last mentioned, absorption coefficient, α10, has measured over wave‐length range 3800–2850A. The value rises steadily from approximately 0.002 at first to 0.52 2850A. coefficient curve continues rise shorter wave‐lengths qualitative observations indicated no maximum far 2400A. No which could be attributed observed 4500A region. NO3 visible are given. In a study using low dispersion influence oxygen on spectrum NO2, noticeable effect observed.
