A spectroscopic study of the mineral paceite (calcium acetate)
Frost, Ray L., Musumeci, Anthony W., & Waclawik, Eric R. (2007) A spectroscopic study of the mineral paceite (calcium acetate). Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 67(3-4), pp. 649-661.
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. A monohydrate (Ca(CH3COO)2.H2O) and half-hydrate (Ca(CH3COO)2.0.5H2O) 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 ~120, 400 and 600 °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.

Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
