“…Though one of the major difficulties associated with studying the spectroscopy of acetates is the large amount of variation in the reported literature [5]. In recent years there has been spectral data published on Mg, Ni, Co, Na and many other metal acetates [1, [6][7][8] though limited data has been published on calcium acetate. One of the reasons for this is the lack of suitable samples.…”

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(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 ~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.

A comprehensive spectroscopic analysis consisting of Raman, infrared (IR) and near infrared (NIR) spectroscopy was undertaken on the newly discovered mineral Hoganite (Copper(II) acetate monohydrate (Cu(CH 3 COO) 2 ·H 2 O)). 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. Two major mass loss steps at 90 and ~220 °C were revealed. These mass losses correspond very well to firstly, the loss of a single water molecule, and then the loss of the acetate anion which quickly decomposes to form carbon dioxide and water.

“…In 480-510 cm −1 , O-C-O in-plane rocking vibration ( 11 ) clearly shows that all acetate ions were not participated in the coordination of iron atoms both as-prepared ferrous acetate and ferrous acetate (99%, reference) (Frost and Kloprogge, 2000). Depending on the environment of acetate ions, the C-C stretching vibration ( 4 ) of acetate ion has been resolved into three different absorption at 930 cm −1 (free acetate ion), 939 cm −1 (monoacetato complexes), and 947 cm −1 (bisacetato complex) (Nickolov et al, 1996;Frost and Kloprogge, 2000).…”
