a Data measured at room temperature (T = 300 K) for the ground state low spin structure. b Signal induced by photoexcitation, measured after 5-ps time delay. c Signal induced by photoexcitation, measured after 100-ps time delay. d Difference between low spin ground state structure determined from X-ray diffraction and high spin structure from our calculation. The colored circles present several selected pairs of Bragg peaks. The positive changes in the intensity of Bragg spots is shown in blue, and the negative changes in the intensity of Bragg spots are shown in red.
