Studies were conducted on Si-doped TiN coatings on stainless steel. The coatings were deposited by reactive magnetron sputtering at different target currents. Prior to deposition of the TiN coating, a buffer layer of Ti (approx 100nm) was deposited to aid adhesion of the TiN coating to the steel substrate. The XRD patterns for c

Acetylene has two C=H groups. It will have two C-H stretching frequencies, the in-phase and out-phase stretching modes. The in-phase (symmetric) stretch occurs at 3374/cm and the out of phase stretch at 3333/cm. Explain why the in phase vibration is located at a higher frequence than the out of phase stretch in the case of a
