The {sup 105}Rh nucleus has been studied by in-beam {gamma} spectroscopy with the heavy-ion fusion-evaporation reaction {sup 100}Mo({sup 11}B, {alpha}2n{gamma}) at 39 MeV. Gamma-gamma-t coincidences and directional correlation ratios were measured. Four rotational bands have been identified with similar characteristics to those in other A{approx}100 odd-proton nuclei. The positive-parity yrast band based on the {pi}g{sub 9/2} configuration and the negative-parity {pi}p{sub 1/2} band, showing large signature splittings, exhibit band crossings at the frequencies of 0.38 MeV and 0.48 MeV, respectively. Experimental Routhians and alignments as well as B(M1)/B(E2) ratios were extracted. The structure of the bands was interpreted within the framework of the cranked shell model and total Routhian surface calculations. {copyright} {ital 1997} {ital The American Physical Society}
