Its like ground state, you should add TD keyword.

Mr. Parida,

There are different methodologies. You could try with IRC or ADMP as well. 

 Dr. Ivanova,

 Thank you for your advice. I am going through IRC calculation, Mr Jamshidi suggests to add TD(calcfc,ts,noeigentest) along with level of theory and basis set but its not working . will you please to suggest the exact route section for optimization of transition state in excited state.

Try: TD(NStates=n,Root=m,x) opt=(calcfc,ts,noeigentest) with the functional and basis set if you are using TDDFT.

n=no of states that you want to calculate

m=the excited state that you are interested in to find the ts

x=singlets/triplets

 Mr. Pratip

 Thanks for your suggestion. I tried with Td(....) whatever you told but the job is terminating after a few second. Its showing " No analytic 2nd derivatives for this method." 

Sorry about that...yeah it has no analytic 2nd derivatives for excited states...try estmfc instead of calcfc..it will just estimate the hessian

or use opt=(calchffc,...) to calculate HF force constants at the initial geometry - it's better than none at all and probably better than estimating -

Thanks to all..
