Materials composed of molecules that absorb large amounts of energy in the form of internal vibrations and rotations will have high specific heats.

Here's why:

Specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat:

q = mcΔT

The heat q flowing into a substance of mass m and specific heat c that experiences a temperature change ΔT is calculated using the above formula.

Materials with molecules that absorb large amounts of energy in the form of internal vibrations and rotations require more heat to change their temperature, hence they have high specific heats. This is because the energy is used up in the vibrations and rotations of the molecules, and less energy is available to increase the kinetic energy (and hence the temperature) of the molecules.
