Ab initio modelling of calcium phosphate clusters and their vibrational spectra
Calcium phosphate and hydroxylcalcium phosphate clusters that model amorphous phase elementary unit
 cells as well as their vibrational spectra were calculated by ab initio quantum chemical method using GAMESS
 code. Normal coordinate analysis was accomplished for phosphate anion, tr...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Calcium phosphate and hydroxylcalcium phosphate clusters that model amorphous phase elementary unit
cells as well as their vibrational spectra were calculated by ab initio quantum chemical method using GAMESS
code. Normal coordinate analysis was accomplished for phosphate anion, tricalcium phosphate and hydroxylapatite.
Calculated IR-spectra and spectra of inelastic neutron scattering were defined in comparison with
experimental data. It was shown that within the suggested approach, vibrational spectroscopy appears to be
a reliable method of verifying the quantum chemical calculated structure versus the experimental data.
Кластери кальцiй-фосфату та гiдроксикальцiй-фосфату, якi моделюють елементарнi одиницi аморфної фази, а також їх вiбрацiйнi спектри були розрахованi за допомогою ab initio квантово-хiмiчного
методу з використанням програмного коду GAMESS. Було проведено нормально-координатний
аналiз для фосфатного анiону, трикальцiйфосфату та гiдроксилапатиту. Розрахованi IЧ-спектри та
спектри непружного розсiювання нейтронiв були спiвставленi з експериментальними даними. Показано, що у рамках запропонованого пiдходу вiбрацiйна спектроскопiя є надiйним методом для
верифiкацiї структур, що знайденi методом квантово-хiмiчних розрахункiв.
