Question

The π-electrons in conjugated organic molecules are described using particle-in-a-box model. According to this model:

		The potential energy inside box is zero
		The wavefunction inside box is zero
		The potential energy outside box is zero
		The wavefunction outside box is infinite

The IR spectrums for diatomic molecules usually contain broad absorption peaks due to the fact that:

		The molecules vibrate
		The molecules rotate
		The molecules vibrate and rotate
		None of above
