- FIN-protons designate the internal two methylene protons of contiguous four methylene chains sectioned by nitrogen atom such as -N-CH2-CH 2-CH 2-CH2-N-. TIN-Protons designate the central methylene protons of contiguous three methylene chains sectioned by nitrogen atom such as -N-CH2-CH 2-CH2-N-. FOU-protons designate the external two methylene protons of contiguous four methylene chains sectioned by nitrogen atom such as -N-CH 2-CH2-CH2-CH 2-N-. TOU-protons designate the external two methylene protons of contiguous three methylene chains sectioned by nitrogen atom such as -N-CH 2-CH2-CH 2-N-. ArMe-protons designate methyl protons attached to aromatic ring. ArHme-protons designate aromatic protons disposed at position ortho to the methyl group. ArHs-protons designate aromatic protons disposed at position ortho to the sulfonyl group.
