Kinetic wave models are used to evaluate a variety of heating scenarios on Alcator C-Mod. In deuterium-hydrogen plasmas heated with ICRF waves in the 40{endash}80 MHz frequency range, single pass absorption coefficients obtained with the METS95 code are compared for the hydrogen (H) minority, deuterium (D) minority, and D-H mode conversion regimes. At the highest magnetic fields available (B{sub T}{ge}8T), the feasibility of off-axis electron absorption of 40 MHz ICRF waves at the shear Alfven wave resonance layer for H majority plasmas is discussed. {copyright} {ital 1997 American Institute of Physics.}
