What is the main difference between rhombic twist and trigonal twist and berry pseudo rotation? If we have a complex like [Co(en)3]3+, how can we understand the main rotation between isomers?
If we want to introduce a material similar to polymethyl methacrylate "with the characteristics mentioned in the next paragraph" that can be added to a precursor and create a composite, which...
