Hi Hoàng Minh, radiative and non-radiative decay rates can be easily obtained using the MOMAP program (http://www.momap.net.cn). Perhaps it would be useful for you to take a look at our recent article: https://doi.org/10.1039/D3CC02534A.

Dear Leandro Mena , can i use your IOp values for any cases? Some options I may not understand well. Thank you in advance.

Dear Hoàng Minh ,

Sure, you can use IOps if you need. We've incorporated a helpful flowchart for quantum calculations in the Supplementary Information section of the aforementioned article. Should you have any additional questions, please don't hesitate to reach out to me!
