There are occasionally some viewing problems caused by browser incompatibility, bugs in software, or our own incompetence (hey, we are organic chemists, not computer scientists! ). We try to make these pages accessible to the largest audience possible.  That means many browsers, many operating systems, many headaches...

We would appreciate it, if you report problems to us. The more details you give us, the better the chance that we will be able to correct these problems, but we offer no promises. 

Of course, we would also be grateful if you report any chemistry errors or things that are not explained clear, and even typos.  Your contribution will help future generations of students using these pages to have more enjoyable experience.  If you submit the form below (it is anonymous) we will be able to respond only, if you provide us with correct return e-mail address.
