A comprehensive spectroscopic analysis consisting of Raman, infrared (IR) and near-infrared (NIR) spectroscopy was undertaken on two forms of calcium acetate with differing degrees of hydration. Monohydrate (Ca(CH(3)COO)(2).H(2)O) and half-hydrate (Ca(CH(3)COO)(2).0.5H(2)O) species were analysed. Assignments of vibrational bands due to the acetate anion have been made in all three forms of spectroscopy. Thermal analysis of the mineral was undertaken to follow its decomposition under a nitrogen atmosphere. Three major mass loss steps at approximately 120, 400 and 600 degrees C were revealed. These mass losses correspond very well to firstly, the loss of co-ordinated water molecules, and then the loss of water from the acetate anion, followed by finally the loss of carbon dioxide from the carbonate mineral to form a stable calcium oxide.
对两种不同水合程度的醋酸钙进行了包括拉曼光谱、红外（IR）光谱和近红外（NIR）光谱在内的综合光谱分析。分析了一水合物（Ca(CH(3)COO)(2).H(2)O）和半水合物（Ca(CH(3)COO)(2).0.5H(2)O）。在所有三种光谱形式中都对醋酸根阴离子引起的振动带进行了归属。对该矿物进行了热分析，以跟踪其在氮气气氛下的分解情况。揭示了在大约120、400和600℃时的三个主要质量损失步骤。这些质量损失首先很好地对应于配位水分子的损失，然后是醋酸根阴离子中水分子的损失，最后是碳酸盐矿物中二氧化碳的损失，从而形成稳定的氧化钙。
