2021年11月2日 · 目前正在尝试用ORCA计算，现在用gaussian计算了S0态的稳定构型，请问我如何用S0态的稳定构型计算S0-S1 以及S0-T1的激发能，输入文件应该怎么输入？ 本帖最后由 zjxitcc 于 2021-11-2 18:17 编辑 看ORCA官方CASSCF tutorial学习如何做CASSCF计算。 大概步骤： （1）做基态CASSCF计算（难度大，仔细看手册）； （2）做SA-CASSCF计算（难度略大，仔细看手册），单重态平均3个根，三重态平均3个根； （3）做多个根的CASCI计算，在此基础上 …

2018年4月16日 · 其实ORCA有比较完整的多参考态的方法，除了常用的CASSCF外， 还有NEVPT2（和CASPT2的理论级别接近，但没有入侵态的问题），甚至 MRCI（或者它的简化版比如DDCI2/3,SORCI等）。 另外，ORCA还能计算基于 CAS波函数的SOC，因而可以计算很多性质 (尤其是磁性)。 再一点，4.0版本的 ORCA也有了自己覆盖很全的相对论全电子基组，SARC2系列。 但我时不时听到有人说ORCA的CAS不好，甚至很烂。 不知道国内有多少人会用ORCA里 …

2022年6月10日 · 雖然於2017年啟動的現行LMP2賽車共有Oreca、Ligier、Dallara與Multimatic等4家供應商，且為求公平起見而一律採用英國獨立供應商Gibson製作的4.2公升V8引擎，但經過數年的競爭後，目前的LMP2級已幾乎成為Oreca獨大的局面：Oreca除了在今年迎接07賽車達成生產100輛的里程碑外 ...
