selfless help, moral support and guidance during hours of need. I would neverforget the company I had from my colleagues and friends.I am very much thankful to Punjab <strong>University</strong>, Chandigadh, for NMRspectral analysis.I am extremely thankful to my colleagues and friends Anil, Dinesh,Mahesh, Mukesh, Rajanikant, Bharat, Narendra, Haresh, Parag, Bhavesh,Sabir, Sanjay, Dipesh, Bharat, Manoj, Nilesh, Mehul, Rahul, Hitesh, Vipul,Bhavesh for their support.I am specially thanks to Mustak, Rohit, Ganesh bhai and Bhailal bhaifor their help during my research work.I feel a deep sense of gratitude to my wife Aekta who had a dream formy doctorate. With their untiring cooperation, which I received in the form oflove, everlasting inspiration and moral support during the period of my study,which was instrumental for the successful completion of the work.The never ending process of enlightenment, love and affection which wasshowered upon me by my Late. Sister Nayana has reached to an important milestone. I am really staggered to realize, just how much efforts has been put in bythem as well as all my sisters and brother.And finally, still there are many more my family Members ,well Wishers,Friends, Relatives, who directly and indirectly rendered me valuable help andmoral strength to complete this academic endeavor. I have deep reverence for allof them.Rajesh G. Rupala
