Hi, 
      I have a problem identifying the proximity of N with O in the above molecule.
Basically i want the count of N-C-O 's ("-" represents that the atoms are bonded, bond type is immaterial, whether single or double) in the above molecule. 

Is the count = 2 or 3?

The same N is accounted for in 2 situations( red and brown) and the same O & C are accounted for in 2 situations (red and blue) 
Is that overlap counted?
