Through the utilization of (algebraic geometry), the specific ways of solutions associated with n basis functions is formally determined as ½(3<sup>n</sup>-1), providing clear evidence that states are compulsory for all molecular configurations. A thorough analysis of the h-RHF states of HZ (STO-3G) subsequently highlights both the continuation of Holomorphic solutions amidst variations in geometry or atomic charges, and the emergence of complex h-RHF solutions at points of convergence. By employing \"catastrophe theory\", these theory converging ways are elaborated upon, certainly the effect of molecular symmetry. We have been two ways getting of result the h-RHF states of HHeH<sup>2+</sup> and HHeH (STO-3G), explanation the structural similarity between systems featuring 2-electrons and 2-holes. Eventually, a realization is executed on the h-RHF states of \"ethane\" (STO-3G) by considering the π-electrons as a two–electron problem, and utilizing NOCI to select an intersection between the ground state energy \"singlet and triplet\" states at vertical structure. The utilization of the \"4-h-RHF\" and \"4-h-UHF\" levels has been employed like a fundamental for \"NOCI\" in order to detect a junction between \"the lowest energy singlet and triplet states\" occurring at a curvature \"angle of 90◦\". This is achieved by approaching the \"π electrons\" in ethylene as a 2-electron dilemma. Subsequently, this outcome is validated within the context of the basis set approximation through variance within the precise \"STO-3G energies\" calculated using FCIQMC, showcasing the ability of integrating \"Holomorphic Hartree–Fock theory and NOCI\".\u0000","PeriodicalId":7717,"journal":{"name":"American Journal of Modern Physics","volume":"3 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141388702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equation on the other hand is to be solved analytically since the exact solution is not easily attainable without the use of mathematical tool especially when it comes to the consideration of the energy eigenvalue and the corresponding wave function because the solution is also always accompanied with a normalization constant often coupled with a condition that requires an arbitrarily chosen quantum number that come up when (l=0) and so on. In general, the analysis reveals the fact that the of trend of KGE involving potential gives a good understanding in the study of inter-molecular structure, diatomic crystals, and such case that involves inter-atomic interaction which is gives very nice idea in the study of bound state in atom.","PeriodicalId":7717,"journal":{"name":"American Journal of Modern Physics","volume":"35 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140420583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
