Dear, Gromacs users,  
I hope this message will find you well.  
I am new Gromacs user. I want to simulate the interaction of 1,2,3-Benzotriazole with water. However, I couldn’t find the appropriate forcefield for BTA.

Could you suggest me where/how to find the appropriate FF for BTA?

Best regards
