I'm assignated to do a lab report which consist of a numerical molecular simulation of water with a very particular water model. My program is already running but my professor didn't talk a lot about the model in particular. At this point -and I think it's totally fair-, we're expected to search/learn most stuff on our own. So I made some researches on the internet about this very particular model and apparently it was invented in 2004 and is explained in details in a paper in the Journal of Chemical Physics. I would like to read more about it just by curiosity. Nevertheless it costs 28$ and I'm a person that doesn't save a single dollar per month, so 28$ would be too much in my case, especially if it's 9 pages long and I'm just "curious" about it. This would be as expensive as a textbook that could help me for a year. I went to the library of the physics campus of my university today and asked if they had the journal. They only have that journal for years 2000 to 2002, unfortunately. So here I am, tempting to write in the lab report "we use the water model XXXX.. :J. Chem. Phys. 120, 6085 (2004); http://dx.doi.org/10.1063/1.1652434" [Broken] without having read or even seen the paper I mention. Maybe it's common in academia to make reference to papers one has never read?! I have in mind "Annalen der phyzik" and people making reference to Einstein maybe without having read the original paper(s). But anyway I think that's strange and would rather not do it. But if I don't make reference to that paper it's like as if I had not searched at all about the paper which is untrue and it does interests me learning more about it. I don't really know what to do about this situation. Is there a free way to see the paper (I wouldn't download it if it's not free, but I want to see it and read through it)?
