Up to a point, yes. But there's a lower limit because photon energy depends on wavelength and you still need to activate a molecular resonance. This is relate

Up to a point, yes. But there's a lower limit because photon energy depends on wavelength and you still need to activate a molecular resonance. This is related to IR being primarily vibrational resonances (like these) while longer wavelengths (RF/microwave) can only invoke rotational resonances which are far less energetic.
