We have analyzed in detail four and five point functions of the string theoryamplitudes, including a closed string Ramond-Ramond (RR) in an asymmetricpicture and either two or three transverse scalar fields in both IIA and IIB.The complete forms of these S-matrices are derived and these asymmetricS-matrices are also compared with their own symmetric results. This leads us toexplore two different kinds of bulk singularity structures as well as variousnew couplings in asymmetric picture of the amplitude in type II string theory.All order $\alpha'$ higher derivative corrections to these new couplings havebeen discovered as well. Several remarks for these two new bulk singularitystructures and for contact interactions of the S-Matrix have also been made.
