Identifying the carbon from C13 NMR spectrum

AI Thread Summary
The discussion centers on the molecule p-phenetidine, highlighting the chemical shifts observed in its NMR spectrum. Aromatic carbon atoms are noted to appear very upfield, while carbon atoms bonded to oxygen (C-O) and nitrogen (C-N) are positioned more downfield, though still slightly upfield compared to carbon-carbon (C-C) bonds. The conversation concludes with a participant expressing gratitude for the clarification and confirming their understanding of the topic.

TL;DR Summary
I am having a hard time identifying the carbons from the CNMR spectrum. I have identified the molecule and the number of peaks.
The molecule is p-phenetidine

In general: aromatic Cs are very upfield, C-O and C-N carbons are more downfield, but slightly more upfield than C-C carbons.

Oh ok thank you I have figured it out now😊👍
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
