Main Question or Discussion Point

Im just trying to figure something out here. Iv been working on some spectra stuff.

Now, when I look at a gas, I see the spectra, but if I turn up the intesnsity, new lines appear? Where do these lines come from, as im looking at the same game, just turned up intensity?

Not sure if I understand what you mean, but I guess these lines were there all the time, they were just less intense. Could be they are from less probable transitions, or from different compounds contaminating the sample.

You'll have to enlighten us as to what "turned up the intensity" means. Brightness knob on the monitor?

You could give us more details, but it seems to me that less probable transitions are starting to show up. But seriously, give us more detail, posting the spectrum would be nice.
