I hate when I open facebook I'm directly asked what's on my mind. First of all it's very invasive, secondly I have only one thing on my mind; my master thesis and the lack of progress concerning it.
Being a chemist I should have forseen this, it should not have suprised me, that my second synthesis poses seemingly insuperable problems. Yet, I am suprised, annoyed and of course tired. Also it is not helping that the synthesis was performed without greater diffulties by a bachelor student.
While I am waiting for the results from my latest attempt I try to convince myself that this has nothing to do with me or my talent as a chemist. Rather the reagents must be too old or contaminated. So far no luck!
Your conclusion from examining your missfortune seems valid to me. It is often rather frustrating than interessting to work with contaminated reagents.
SvarSletBut keep in mind that if jupiter conceals a star in the sign of orion and the moon looses some altitude in his orbit some molekules are too lazy to do what you tell them to. ;)
