It’s not just a talk :)

Somehow, i wanna start to write about a little dream,

food analysis lecture.

Days a go, when i was goofing off w/ my friend, 

i said : “I wanna be like Prof. Dedi Fardiaz”.

Oh c’mon, it’s all talk, you can check my midtest’ score out. 

I scored the worst.

Prof. Dedi Fardiaz.

He’s a hell of lecture, i swear. 

He’s a simple man and really something.

Yes, he’s one of great lectures in

Food Science and Technology Departement, 

Bogor Agricultural University.

By the way,

Someday, he teached us about Spectroscopy IR.

There is IR spectrum like tachycardia.

At the time, he explained that soooooo simplyyyyyyy. 

OH GOD. There was somethin’ wrong, haha :D (wondering)

After class, when i reviewed that chapter,  actually blank :D

Then, I tried hard to understand how read the spectrum, 

and finally i got it basicly (super basicly  :P), like in 6 hours :D

Generally, IR spectrum is divided into 3 regions.

1. The Functional Group Region, 4000-1300 cm^-1 _­.

The C-H stretching bands occur in the region of 3300 to 2800 cm^-1 , sometimes it’s not attended :P

The O-H and N-H stretching frequencies fall in the 3700 to 2500 cm^-1 region,with various intensities

The absorption bands at the 2700 to 1850 cm^-1 region usually come only from triple bonds, such as CºC at 2260 to 2100 cm^-1,  CºN at 2260 to 2220 cm^-1

The absorption bands at 1950 to 1450 cm^-1 region, usually come from double bonds, such as C=O stretching bands are strong and occur at 1870 to 1550 cm^-1

2.  The Fingerprint Group Region, 1300-910 cm^-1 _­.

This region strongly indicates purity of compound.

Detailed interpretation of IR bands in this region is difficult.

For example, esters’ not only show their carbonyl C=O stretch

at 1750 to 1735 cm^-1, but also exhibit their characteristic absorption at 1300 to 1000 cm^-1 from the couplings of C-O and C-C stretches.

3.  The Aromatic Group Region, 910-650 cm^-1 _­.

This region do not necessary come from aromatic compounds, 

but amines and amides also contribute in this region.

Looooh ko out of the topic, ok, ok, it’s just short literature and absolutely you need to read more :P

. . . . . .

I often hold myself disable to be Excellent Lecture like Prof. Dedi Fardiaz, there is disbeliefe

How can? Can i? Will i?

Ok, THERE IS A WILL, THERE IS A WAY (#oldsaying)

It’s gonna be true, iiiiiiffffff,

I study hard

Do not be a sissy again : my Friend (call him KOKOP),

he said, “Calon dosen ko cengeng? Katanya mau gantiin Pak Dedi :P”

Quit whimpering about trifles

C’moooon, it’s not just a talk

Diiiiin, Chiiiiiin uuuuup :)

Well, Let’s see what can i do :)
