Yeah, I thought of that myself. I was more concerned with the surrounding air taking up heat.
Won't happen, that's not how IR works ![]()
IR directly vibrates molecular bonds that have changing dipole moments. Basically, they interact with "magnetic fields" that are constantly changing.
So, when you have these proteins with carbon-nitrogen-hydrogen bonds and all this other stuff, every individual atom is wiggling around in the molecule. Each bond has a specific size, and a specific amount of energy that it takes to wiggle the bond based on the number of bonds between any two atoms (single, double, triple) as well as the mass of each atom. That means that N-H bonds wiggle at specific frequencies, for example, that change based on what else is connected.
The IR increases the amplitude of these oscillations in the bonds (bends, stretches, scissor action, all sorts of movements) which adds kinetic energy directly to the target molecules! There is zero air interaction, apart from some carbon dioxide absorbing a little bit of the IR as well. It doesn't affect Oxygen gas or nitrogen gas.
So basically, you are going to be heating up your molecules and the outside air will not have any significant effect at all, regardless of temperature.
That's why, if the sun is out, you can sometimes take your shirt off in cold weather and actually feel warm where the light is hitting you!
That's some badass science, right?!
