The polarization charges in {sup 44,46,48}Ti are studied by the microscopic particle-vibration model and used to investigate the electric quadrupole transitions of the yrast terminating bands. The validity of the commonly used empirical effective charges in the pf shell-model calculations is confirmed. The quadrupole transition probabilities B(E2,I{yields}I-2) and electromagnetic moments are reasonably well reproduced compared with experimental results. It is found that a globally decreasing B(E2) is accompanied with convergence of valence particles into the 1f{sub 7/2} shell when approaching the terminating states. The I=6{sup +} state in {sup 48}Ti shows an exotic behavior with an irregularity of B(E2) and sign change of electromagnetic moments, which is related to a neutron-dominant prolate shape.
