A comprehensive analysis of high spin band structures for odd mass I nuclei is performed using Triaxial Projected Shell Model (TPSM) approach. Using suitable values for the relevant parameters, the estimated energy spectrum of odd mass I agrees well with the experimental results The potential energy surfaces reveal that the isotopes are heading from 
-softness towards rigidity. The current analysis further revealed that the typical band crossing along the yrast as well as the yrare line is caused by the three-quasipaticle band crossing the one-quasiparticle band. Further, transitional probabilities [B(E2) and B(M1)] have been computed and found to be consistent with the available experimental data. Chirality in 
I has also been discussed.
