> Wavelength range of Hydrocarbon spectral emissions

  1. Jun 29, 2009 #1
    I was checking the NIST site with their Hydrocarbon line database
    search utility, and the frequencies of the lines for CH, CH2, and CH4
    are on the order of 10^11 Hz approximately. That leads to wavelengths
    that are much larger than the visible region. Am I reading the search
    results correctly, i.e., do these hydrocarbon molecules really have no
    emission lines in the region 200 nm to 1000 nm?

    Also, i've noticed that people who post here have their e-mail address
    displayed as scrambled (to prevent spammers i guess). Is one's e-mail
    address automatically displayed as scrambled or is there an option
    somewhere to do that?

    Thanks =)
