Detailed analysis of zero-filled, resolution-enhanced spectra (peak picking, integration, and multiplet
analysis) was performed using Broker's WIN-NMR software for PCs.
The protons at C-2, C-3, C-6 appeared as multiplets
and showing both the germinal and vicinal coupling, reason is that this molecule has a basket like shape, therefore, H are positioned towards the inner core of the basket and get shielded.
45 ppm peaks are attributed to CH3 proton present in these dyes, 10H and 8H multiplet
peaks are present at 7.
1 ppm corresponds to the four glycerol methylene protons in the triglyceride molecule, while the small multiplet
18 (5H, multiplet
, H-1''/ H-2''/H-4'', H-5''/H-6''), 4.
The signal of benzyl ring resonated in form of multiplet
at d 7.
The methine proton attached to the asymmetric carbon is a multiplet
36 (br s, 8H, i) s, singlet; d, doublet; br s, broad singlet; m, multiplet
The number of Stark levels for each multiplet
9 ppm, while the aromatic protons appeared as a multiplet
in the range of 6.
4 nm, a prominent oxygen emission multiplet
within the lightning spectrum.
0] values in any F-spin multiplet
have identical [N.
