Are there DOI available for the three references listed in this new code?

@hanli-liu, @npedatella
Do you have DOI references for these reaction rate calculations?
There was a problem hiding this comment.
The DOIs are:
doi:10.1021/jp972365k (Fernandez et al. 1998)
doi:10.1029/2002GL016720 (Duff et al., 2003)
doi:10.1029/GM087p0001 (Roble 1995)
Also note that the Fernandez paper does not give the rate coefficients. These were calculated from the data in the paper by John Orlando, Doug Kinnison, and Jun Zhang. I am note sure if this should be mentioned or not.
