Attosecond Fourier transform spectroscopy with attosecond pulse trains is implemented for observing ultrafast quantum wavepacket dynamics in diatomic molecules. We use attosecond-pump/ attosecond-probe scheme to measure the electronic and vibrational response of diatomic molecules in the intrinsic timescale of the electron. This is the first step in understanding or controlling chemical reactions on such a timescale.
