Was feeling a little lazy today, so didn't do much (or any, rather) lab work. managed to get my imine NMR, which was quite nice. only problem is the existence of some water, which might cause the reverse reaction to occur. i'm finding it funny/mildly upsetting that my product still contains water despite the great pains i took to keep the reaction system anhydrous. probably that happened during the work-up step. should use distilled solvent next time.
but like i said before, this reaction was the easy one. the subsequent reaction which i'll do on thursday (not tomorrow due to classes) is the hard one. well, the reaction itself is easy, but the following column is hard. hopefully, fresher reagent leads to a better reaction, and i'll have more success this time round.
other happenings this week...TA is all but over. except for a few (like 6) people who wanted to redo their column, the lab was practically empty. between my friend and i, we had 3 students each. how's that for slack? luckily, there weren't any major issues, and we even ended early. last thing for the lab module is the test next week. the procedure is actually pretty easy. what's more, the lecturer was even nice enough to upload the exact experimental procedure a week in advance! that's why i say whoever is smart enough to fail really deserves it. of course, there are steps that, if done wrongly, can cause errors which can't really be recovered from. i just hope that they don't get nervous and mess up.
today, i got a huge weight off my shoulders by talking to my japanese lecturers. since i was in arts, i decided to call on my japanese 1 and 2 lecturer as well. by some stroke of good luck, i caught him just as he came back from somewhere else. chatted with him for about half an hour or so, and i don't know...even now, i kind of miss him and his teaching method. actually, i was kind of surprised that he made time to chat with me, especially since he doesn't teach me any more. the chat with my current lecturer was a bit more...serious, i think. basically told him what i thought about the mid-term, and some other stuff. while he didn't give any new advice (study, revise, ask the teachers if you don't know), i still feel better after talking to him. guess it's because he's more aware of my viewpoint.
i think i'm crazy. or at least more irrational than normal, if recent events are anything to go by. now that i think about it, part of the reason i didn't want to do lab work today was also because there was a (or rather, that) certain someone with whom i wanted to spend a little more time. see? irrational. bad for my health, i think. but still...i think i can juggle stuff well enough.
let's see...anything else? tuition with army boy will end after this week, as his exam is next tuesday. or we might have a couple more sessions for paper 1 and 2. for TKGS girl, her school is still teaching, so we still have to cover some stuff, like rate of reaction. nothing that difficult, i think. don't think i missed anything out, but if i did, i'll probably mention it in another post.
