It is said rotational spectra of homonuclear diatomic molecules cannot be observed but why? In the book it is says There will be no dipole component change if the molecule rotates so it will not interact with radiation. for homonuclear diatomic molecules. What relation do change in dipole compo...

I am new to spectroscopy, so I am not sure how my questions are perceived. I just want to make sure that I am not lost, so any kind of suggestion is welcome. I am interested in the infrared absorption spectrum of molecular nitrogen and oxygen. I thought it would be more streamlined to obtain this...

Is the following the correct designation (S) for the chiral carbon? The rules say to go one at a time by each rule until you find an answer. 1a. Higher atomic number 1b. Go down the chain until a difference is found Higher atomic mass In this case, even though the 13C is a higher atomic mass t...
