1. What happens when NMR active nuclei is irradiated with radiowave frequencies ?
The question is from structural biology(NMR spectroscopy).
Solutions
Expert Solution
Into nuclear magnetic resonance,which is detected with sensitive radio receivers the intramolecular magnetic field around an atom in a molecule changes the resonance frequency,thus giving access to details of the electronic structure of a molecule and its individual functional groups.as the field are unique or highly characteristic to individual compound in modern organic chemistry practice,NMR spectroscopy is the definitive method to identify mono molecular organic compounds.

Question 3. This
question looks at what happens when markets do not clear. Suppose
that the metropolitan museum of New York will display the works of
Leonardo Da Vinci for one week. Each day one hundred people can
view the exhibition so supply is fixed at that number. The Museum
sets an admission price of $10.
Suppose that the
demand to see the exhibit each day is Qd = 400 –
10p.
How many people want to attend the exhibition...
