Hello,

I have a difficulty to solve my homework,(I know that I should do it myself, and I am trying), would someone be kind and help me, please?

this is my first homework and it's very important.

questions 1.3 and 1.4 in the attached file.

Thank you

1.3 does not look not hard. They give you the formula to use and even the numbers to plug in.

The only complication I can see is that they give spectral data in wavenumbers (cm-1) rather than frequency. You just need to remember that wavenumber (1/λ) = ν/c, so you multiply wavenumber by c to get a frequency.

Can you work out an answer for the first bit, i.e. for H3+ at 1000K? What do you get? If we can agree on that you should be able to work out the rest, I think.

1.4 looks trickier, I must admit. I'll need to think about that one a bit.
