Structural parameters and potential energy curves were calculated for 3-(4-chlorophenyl)thiophene (CPT), 3-(4-trifluoromethylphenyl)thiophene (TFMPT) and 3-(4-methylphenyl)thiophene (MPT) at the HF/6-31++G**,HF/6-311++G**,B3LYP/6-31++G** and B3LYP/6-311++G** level of theory using Gaussian 03 program packages. The global energy minimum of each potential energy surface (PES) was referred to as zero. The potential energy curves, calculated by B3LYP/6-311++G** level of theory of CPT and MPT molecules, have similar characteristic.
