O 1s X-ray emission and X-ray absorption spectroscopy is applied to probe hydrogen bonding of water (D(2)O) in 3-methylpyridine. Owing to element selectivity of X-ray spectroscopies the electronic structure of water in the binary mixture was observed selectively. Based on the observed spectral changes associated with hydrogen bonding in O 1s X-ray emission and X-ray absorption spectra, we have investigated the hydrogen bond of the mixture sample over a wide range of D(2)O concentrations (X(D(2)O) = 0.02-1.0) at room temperature under atmospheric pressure.
O 1s X 射线发射和 X 射线吸收光谱被应用于探测 3-甲基吡啶中（D(2)O）的氢键。由于 X 射线光谱学的元素选择性，可以选择性地观察二元混合物中水中的电子结构。基于在 O 1s X 射线发射和 X 射线吸收光谱中与氢键相关的观察到的光谱变化，我们在室温、常压下，在很宽的 D(2)O 浓度范围内（X(D(2)O) = 0.02-1.0）研究了混合物样品的氢键。
