<div>Hi, all</div>
<div> </div>
<div>I am using the CASPT2 to calculate the single point energy of the molecules, but i do not know which method RS2 or RS2C in the CASPT2 is better.</div>
<div>If you know, please tell me why, thank you!</div>
<div>PS: Only three elements C O H in my molecules.</div>

<div>Thanks advanced! </div>
