NAME: 1,2-butanediol dinitrate
FORMULA: CH3CH2CH(ONO2)CH2(ONO2)
AUTHOR(YEAR): Barnes(1993)
T: 298K
λ: 250-320nm(fit)
BIBLIOGRAPHY: I. Barnes, K.H. Becker, and T. Zhu, "Near UV absorption spectra and photolysis products of difunctional organic nitrates: Possible importance as NOx reservoirs", J. Atmos. Chem. 17, 353-373 (1993); DOI: 10.1007/BF00696854
COMMENTS: Absorption measurements using a diode array spectrometer; spectral resolution 0.7 nm

A least-squares fit of the spectrum performed in the range λ = 250-320 nm and using the equation

σ(λ) = exp(a λ2 + b λ + c)

led to the parameters a = -6.217×10-4, b = 0.3025, c = -80.41 (λ in nm)
