  Expressions for the two-dimensional Stimulated x-ray Raman Spectroscopy
(2D-SXRS) signal obtained using attosecond x-ray pulses are derived. The 1D-
and 2D-SXRS signals are calculated for trans-N-methyl acetamide (NMA) with
broad bandwidth (FWHM ~14.2eV, 181 as) pulses tuned to the oxygen and nitrogen
K-edges. Crosspeaks in 2D signals reveal electronic Franck-Condon overlaps
between valence orbitals and relaxed orbitals in the presence of the core hole.
