I was doing these experiments for a comparative study and ended up getting spectrum like the two I have attached. The big problem is that I can not identify the bands with head at 530 nm and 365.8 nm. I have been able to find CN violet band and C2 bands in green region. But could not do much headway thereafter. I am not a spectroscopist and this complicates the problem further. I am also attaching two images from different portions of the spectrum. I have tried to match with Ar, CO, CO2, F, CN, C2, CH, OH but nothing is working. Any help or clue leading me to the proper direction will be highly appreciable.
