  We explore the entire form of S-Matrix elements of a potential $C_{n-1}$
Ramond-Ramond (RR) form field, a tachyon and two transverse scalar fields on
both world volume and transverse directions of type IIB and IIA superstring
theories. Apart from $<V_{C^{-2}}V_{\phi^{0}}V_{\phi ^{0}}V_{T ^{0}}>$ the
other scattering amplitude, namely $<V_{C^{-1}}V_{\phi^{-1}}V_{\phi ^{0}}V_{T
^{0}}>$ is also revealed. We then start to compare all singularity structures
of symmetric and asymmetric analysis, generating all infinite singularity
structures as well as all order $\alpha'$ contact interactions on the whole
directions. This leads to deriving various new contact terms and several new
restricted Bianchi identities in both type IIB and IIA. It is also shown that
just some of the new couplings of type IIB (IIA) string theory can be
re-verified in an Effective Field Theory (EFT) by pull-back of branes. To
construct the rest of S-matrix elements one needs to first derive restricted
world volume (or bulk) Bianchi identities and then discover new EFT couplings
in both type IIB and IIA. Finally the presence of commutator of scalar fields
inside the exponential of Wess-Zumino action for non-BPS branes has been
confirmed as well.
