BIBLIOGRAPHY: J.B. Burkholder, R. Talukdar, A.R. Ravishankara, and S. Solomon, "Temperature dependence of the HNO3 UV absorption cross sections", J. Geophys. Res. 98(D12), 22937-22948 (1993); DOI: 10.1029/93JD02178
COMMENTS: Measurements of the absorption cross sections at 240, 260, 280, 315, 337, and 360 K relative to those at 298 K (using a diode array spectrometer with a resolution of ∼0.4 nm)

The data for 260 K have been calculated using the absolute absorption cross setions measured at 298 K, the parameterization of the temperature dependence by

σ(T, λ) = σ(298 K, λ) × exp[B × (T - 298)] and the temperature coefficients B:
