Stretched Gelatin Phantom for Detection of Residual Dipolar Couplings in MR Spectra and Data Analysis of Carnosine

Figure 4

¹³C spectrum of the gelatin phantom in magnitude mode. Solid lines indicate the position of carnosine signals in ¹H decoupled high resolution NMR spectrum. The measured total couplings are indicated by blue dashed lines for the peaks of Cα at 56 ppm and C5 at 118 ppm.
