The gaseous molecule CrPO, has been investigated in the course of a high-temperature massspectrometric Knudsen-cell study of the vapours over an europium-chromium-phosphorus-oxygen system. From the enthalpy of the equilibrium reaction CrPO,(g) = CrO(g) + PO(g) and appropriate ancillary data, the atomization energy of this molecule has been determined. In addition, the dissociation energy of CrO(g) has been obtained through the study of the gaseous exchange reactions W03(g) + Cr(g) = W02(g) + C r a g ) EuO(g) and and compared with previous results. 436.2 f 8.9 kJ mol-'. was derived as: L\H&[CrPO,(g)] = 217.6* 13.0 kJ mol-'. The dissociation energies obtained are: (CrP02) = 1438.4* 12.2 kJ mol-', and D F ( C r 0 ) =The appearance potential of CrPO,(g) was determined to be 8.0 f 0.5 eV, and the heat of formation
System-level failures and unmet patient needs are modifiable risks for readmissions. Development and reliable implementation of a COPD care bundle that mitigates these failures reduced COPD readmissions.
The polarized ion model has been applied to calculate binding energies, equilibrium configurations, and force constants of the gaseous alkaline-earth dihalides. The capability of the model to predict bent structures has been proved and good agreement between experimental and calculated bond angles as well as binding energies has been achieved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
