# UV-VIS spectra of n-decanes

I was wondering if anyone knows where I can find UV-VIS spectra of the n-decanes. Specifically tetradecane and dodecane. I can't seem to find such information using my regular search methods, so I was wondering if there was a common database that contains such things that I am simply unaware of (likely).

All I really need to know is if these chemicals will absorb radiation with wavelengths between 355-375 nm. A source to back this up will only help.

Thanks, Sam

To the best of my knowledge, ordinary alkanes do not typically absorb anywhere in the UV/Vis region. The organic molecules that do typically contain electrons in $\pi$- or non-bonding orbitals, which have energy level transitions corresponding to UV/Vis wavelengths. That said, I did find one paper1 describing absorptions around the far UV ambit, where $\lambda < 200\mathrm{nm}$.
If you put http://dx.doi.org/ in front of any DOI, it gives you the permalink to the article. It's not a big deal, but it saves having to edit if the site for the journal moves. –  jonsca Aug 6 '14 at 21:48
