Chemical shifts in 31P-NMR spectra of linear polyphosphates were studied. In each polyphosphate species tested, the sum of signal intensities of the internal (core) phosphate groups was proportional to the concentration of each polyphosphate, but the contribution of such groups to the total intensity of the signal decreased with increasing the length of the polyphosphate chain. An equation for estimating the polyphosphate chain length in biological objects taking into account a decrease in the 31P-NMR spectral intensity is proposed.
研究了线性多磷酸盐31P-NMR谱中的化学位移。在每个测试的多磷酸盐物种中，内部（核心）磷酸基团的信号强度总和与每种多磷酸盐的浓度成正比，但随着多磷酸盐链长度的增加，这些基团对信号总强度的贡献降低。提出了一个考虑31P-NMR光谱强度降低来估算生物物体中多磷酸盐链长度的方程。
