Question
Carbon tetrachloride is neither microwave nor IR active (it does not show up in either spectrum).
Hot band vibrational transitions occur at the same frequency as the fundamental transition.
Generally, the rotational constant B decreases as the vibrational quantum number, n, increases.
The FTIR spectrum of HCl has a Q-Branch
The px-orbital is an eigenfunction of the total angular momentum operator.
For 3D motion, it is not possible to measure the total angular momentum and the angular momentum about
the z-axis simultaneously
Explanation / Answer
Carbon tetrachloride is neither microwave nor IR active--- False
The Carbon tetrachloride shows C-Cl streatching at 800 cm-1.
Hot band vibrational transitions occur at the same frequency as the fundamental transition. --- False
In molecular vibrational spectroscopy, a hot band is a band centred on a hot transition, which is a transition between two excited vibrational states, i.e. neither is the overall ground state.
Generally, the rotational constant B decreases as the vibrational quantum number, n, increases. ---True
The FTIR spectrum of HCl has a Q-Branch ---True
The px-orbital is an eigenfunction of the total angular momentum operator.---True
For 3D motion, it is not possible to measure the total angular momentum and the angular momentum about
the z-axis simultaneously ---False.
