Surely this means that: WebHMDB ID: HMDB0000228. Compound name: Phenol. Spectrum type: 1 H NMR Spectrum (1D, 600 MHz, H 2 O, experimental) Disclaimer: While we have made our best-effort to label most spectral peaks, certain spectral features may not be fully annotated in all NMR spectra. WebNMR spectroscopy is one of the most powerful methods for investigating hydrogen bonding interactions both in solution and in the solid. Thus, 1 H and heteronuclear chemical shifts, coupling constants, solvent and deuterium isotope effects on chemical shifts can provide evidence of hydrogen bonding [ 5 ]. swedish combat boots
